Spell and equipment graphics

I was curious about these i have tried watching some of the tutorials like the one about how to edit the shield graphic. https://www.ff6hacking.com/forums/thread-3204.html

i found a site with the graphic tables from ffvi and a whole bunch of other games

So this one has the some of the spells for this game and i have always really liked the final fantay iv fire 3 found in the following

So i had quite a few questions lol

1 I tried to get the weapon animations off of the sprite viewer the map says they aren't compressed so how do i save them as a bin to view on the yychr?   
2 In the video it said i needed a save state from when the shield was shown so i need to get a shield block save state to edit the shield or whatever item? or maybe i really misunderstood that part i use snes9x-x64 do i need a different emulator?

So my questions are how would this be done lol and second on a scale of like 1-10 how insane would it be to move spell and weapons from those tables into the game

Hopefully im not spamming to many posts and stuff
