I like the theme above, it would be excellent for the menu music, or a recurring theme in the cinematography of the full theme when there are quieter/more elegant parts.
But, I would love to have something like. . . Dang, I don't know. OH WAIT! Latin wasn't enough last time, it should have full blown CHANT in it, I'm talking GREGORIAN CHANT, like, for real dog, like monks and jazz, those guys you know, if done right it can make some good transitional music/recurring theme.
But for the actual epic part, something symphonic and brassy, don't be afraid of the softs and strings/woodwinds though, and don't forget the marimbas and percussion.
