A Different Sort of Kefka Hack

Hello, I have an idea for a rom hack based around Kefka. I have seen ideas for hacks based on Kefka's story before, but never one quite like my idea.
My idea takes place in the present, not in the past, and it happens after the end, when Kefka is supposedly dead. It turns out that Kefka's defeat was actually an illusion he created in the minds of the protagonists. He said he would destroy all of existence, but there's a part of him that's saying, "Wait, wait! If I do that, then what? Then who will I destroy? And don't I live in existence? What about me? I love me, and I don't want anything bad to happen to me!"
He has a fight with himself, almost literally, with his little sprite facing left or right depending on which "side" of him is talking. Eventually, he decides to fake his death, so that people will start rebuilding delicious buildings and making tasty babies that he can destroy much later. The hard part, he thinks, is being patient with the puny humans. Stupid, slow, so very slow humans.
As you can imagine, waiting in the rubble of his destroyed tower isn't much fun. It's really boring. So he decides to make himself "weaker" on purpose (choosing to limit his magical power), so that fighting monsters is a challenge. Eventually, fighting monsters loses its charm, so he starts visiting human settlements. He mostly visits to see what kind of reactions he'll get, like how a sibling will bother another sibling just to see the reaction. He uses his powers to freak people out, and make completely untrue stuff up about himself.
Like,
"Oooh! I am the ghost of your father!"
"I am an angel of the Lord! So, you better do what I say!"
"Every time you call me a clown, I steal a little bit of your SOUL!" (He certainly doesn't think his clothes look clownish!)
But in his visits, sometimes he comes across a person or creature that seems markedly different to the rest (at least to him.) In no particular order, here are the "party members" he acquires (and his thoughts on them) on his journeys,

(All names are just the names Kefka uses for them.)

Stupid Kid - This dumb kid doesn't think I'm that great, no matter how many trees I burn down. Even though the adults all cower in fear before me, this STUPID kid just laughs at me! I threatened to burn his parents, but he says he's an orphan. Hmm, no wonder he's so stupid, he doesn't have any parents to tell him how to act. Hey, wasn't I an orphan...?

Stupid Dog - This foul, stinking mutt is as moronic and ugly as they come. He barks when there isn't anyone around, he growls at me, he nips at my leg. GRRRR! I HATE HATE HATE THIS DOG! Hmm, I really should kill this dog, but every time I try to kill it, it whimpers at me, and licks me. What IS up with this dog? It puzzles me to no end.

Stupid Bird - This obnoxious, yet colorful, parrot copies MY beautiful voice, and copies MY words! GRRRR! SHUT UP! That's MY voice! Mine! The only reason I'm even keeping you alive is because you match my outfit. You look so becoming on my shoulder like that. If only I could get you to be quiet.

Stupid Lady - This hysterical woman won't leave me alone. For some reason, she thinks I'm her child that she lost recently. Her mothering of me can be very irritating (she doesn't seem to realize I'm an adult,) but on the other hand, I'm glad someone is finally paying attention to me.

Stupid Hobo - This stupid, half-blind, homeless idiot talks about nothing but conspiracy theories. Normally, I'd just set him on fire, but his idiotic commentary is priceless. Besides, he said my feathers look pretty! I can't kill someone who compliments my headdress.

Stupid Geezer - This senile old fool has dementia. Apparently, her relatives don't visit her anymore (I can see why.) However, she showers me with praises and attention. She says she's impressed with "what the young people like you are wearing these days." Once again, I can't kill a someone who compliments my headdress.

Stupid Jerk - This JERK is just plain mean to me! Even after demonstrating my powers, she is still fearless of me, as if she has a death wish. Part of me wants to throw her into a bucket of sulfuric acid, but there's another part of me that wants to find out where, exactly, she's getting her death wish from...

Stupid Ghost - This annoying ghost said I poisoned him in life. GRRR! Every time I try to sleep he whispers nonsense into my ear! He says he won't go away until I feel remorse about the things I've done... Psst! Fat chance! Stupid ghost, I'll show you!

Stupid Minion - This is one of those peons I used to boss around back when I was merely a general. Apparently, this idiot is still loyal to the death for me. Wow! And he does ANYTHING I tell him! Hit yourself in the face! Give yourself a wedgie! Flip off your own grandmother! Teehehehehe! Huh, why is he so loyal to me, even if he knows I'm bad...?

Stupid Dude - This moron in mismatched clothes thinks I'm really cool, so I guess he's not such a moron. I mean, he's still a stupid, puny, mortal human (yes, I am immortal!). He's always asking me to show off my magic tricks because they are "rad," and he says my outfit "really sticks it to the man." I asked him who the "man" was, and he said it was "the establishment." So I asked him what "the establishment" was, and he said it was "society." Hmm, so he dislikes society, huh? Maybe we're not so different...

Stupid Octopus - This octopus says his name is "Ultros." Haha! A monster with a name! How absurd! He makes me laugh so much, that I simply MUST keep him around.

Stupid Moogle - All I did was give him one kupo nut, and now he WON'T STOP FOLLOWING ME!

Stupid... Me? - This dark shadow looks just like an outline of me. Wha? Whaaat? What is this thing?

All party members are much, much weaker than Kefka. Almost like dead-weights at first. However, unlike Kefka, they do possess great "healing magic" and "defensive spells." But Kefka is the only character who can really do any major damage to the monsters. Kefka has minor healing spells that he uses at first, but later on their healing becomes necessary. The best late-game formation is to have Kefka in the front, and all other characters in the back, because he has the most hit points and defenses. At first, you can get by without protecting the other characters, and just have them be dead all the time, but later on it becomes important to keep them alive.

Kefka is very prone to reminiscing about the past, and how things could be, and what it might be like to be in another character's shoes (like Terra, or Edgar, or Cyan, ect ect.)
Is possible to have the appearance of the World of Ruin switched with the World of Balance? That way the World of Balance appears after Kefka reminisces about the calamity he caused, and wishes he could have done something different. It wouldn't be because he actually changed anything, but rather because of him now noticing the greenery that has been reappearing recently.
Most of the game would be about Kefka slowly recovering his own humanity, and rediscovering things like beauty, love, friendship, loyalty, and all that good stuff. Of course, even at the end he still looks like a clown, because he just wouldn't be Kefka anymore if he didn't, now would he?

I know nothing about code or hacking beyond the superficial. I use a Mac, so I can't make use of any FF6 hacking software. But I am a professional writer and illustrator by trade, so I can write dialogue and scenarios, and create sprites and color schemes as needed.
