Final Fantasy Hacktics

So i added the sprite into the game and replaced ramza so hes the main character so to speak. I d like to make a new class for him, one where he can transform into a beast. Not sure if this is even possible as ive looked through the FFTPatcher and i cant seem to figure that out. I think id have to replace a class. which would be fine. Any help int he right direction would be great i just started out

It isn't possible.

Youd have to some serious ASM hacking for that.

ok thanks for the info. I figured id just ask. what about just taking ramzas starting skills and weapon and chaging it to a gun? can that be done with the FFTpatcher? its seems you can only change job related and not character related abilities? or maybe im missing that
