Given how little personality the main character is given in these games due to the social link system, I don't see to much of an issue with making him so similar to P3's.
Aegis may or may not be a good Idea. I don't really think it should be a connected story at all, given the ending of P3: FES, but if they do a whole 'Mai-Otome' and make it An alternate Aegis, so to speak, it could turn out well.
But then again, I love me some Aegis. :love:
