I love the idea of team names, and yours are great! Seriously, that would be such a neat set of easter eggs.

The FE fanboy in me can't help but point out, though, that Hero of Blue Flames is Ike's Japanese title, and it is translated to Radiant Hero in the English game.

As for titles of my own:
: Second Banana No More
: Angelic Captain (his official title is so wordy!)
: The Radiant Hero (why "of legend" was added to Ike's title but Marth's was just The Hero-King doesn't make much sense)
: Grandmaster Tactician
: The Electric Mouse
: F-Zero to Hero ( or he could steal Falco's title and step it up to Space Race Ace)
: Heir to the Monado
: Super Fighting Robot
