Kefka vs Leo???

Hey there! I was messing around with my hack yesterday and came up with an idea... I would REALLY like the battle between Kefka and Leo to be more serious. Like Leo have more stats(I know how to do that) and for Kefka to be on par with some bosses from the WOR and instead of using his enemy sprite, use his character sprite instead.

So my main concern is how to make him use the character sprite instead. And if I can, will he kneel when he is wounded or near dead like normal? Hope to get a reply soon! THANX!
