I haven't thought about balance as of yet and I'm considering releasing a version where I just replace units. E.g. Swapping Inness with level 2 Wil, and also a version where I try my best to balance it. I've barely done any playtesting yet (Up to chapter 2) so I may have to make changes when I play through it so that everyone is recruitable and the game is beatable.
I'll happily use the sprites when you finish them, thanks.
I like these changes however most of my experience with hacking is in nightmare. I'll need to learn how to add new sprites to the game and add them to the CC characters without just replacing them as this would mean that characters in the story get replaced. Although thinking about it, Queen Karel of Jehanna, Mother of Guy sounds pretty good to me.
