If they do DLC Echo Fighters, i'm all on-board for Heroine, I just wonder who they would use though.
Erdrick and Sofia are obvious replacements for Erdrick and Solo, but... who else would they choose? It would be weird having the IX and X female heroes without their male counterparts, and there are no exclusively female heroes in the mainline games.
Brought this up before the website update, but I figured, Sofia (IV), Female Erdrick (III), Ann Lucia (X), and Female Celestrian (IX) would work as the other 4 alts.
