I've been reading the topic, and I have a suggestion about the fate of that character. Go the super robot wars way, where you can change the fate of certain characters if you do it right. In a FE game, that could mean either suports (Fates do it) or maybe with finishing x goal in y turns? Something like that. And you could apply the same with the fate of that other character whose sprite could be troublesome after that happens. Just tossing some ideas, this hack looks really interesting.
