they should totally play the black mages version of the boss theme tune :P

and they should do something with the summons!! the summons are so poor in this game! kotr is cheap but that aside, once you get bahamut zero, there is no other need for any other summon in the game. even if something has an elemental weakness to leviathan, why use him when bahamut zero will always do 9999hp damage anyway. i dont think much effort was put into there summons
