Swap which characters share palette

Hey C-dude thanx for this, was looking for info for this but couldn’t find anything, sounds very complicated lol will need to look into it. Ff6tools can swap pallets over but not shared palettes trying to create a paladin Cecil but palettes are an issue as can’t use terras which has best suited colours. Also if I swap umaro out for someone else and give them abilities (fight, magic) will he be controllable?
