Well, you're right in saying that I'm unfamiliar with that way of staging a battle, yes; we have no way to summon the souls of the dead, where I'm from. At least, not intentionally, and not in any way that won't end horrifically. However, I will say that even if the numbers are reasonably low, I can certainly see where having that many powerful people would result it flat-out warfare, yes.
What sort of legendary heroes are we talking about, exactly? I doubt they're the same, given that very few in this place seem to know about Amestris and I wouldn't be surprised if the legends we have are completely different, but we do have stories regarding the old world - kings and warriors and prophets and the like, who shaped the past/provided pathways to form the present. Is that the sort of thing you're referring to?
