No, it'd be better without romance.But i think it would be nice if they can put in subtle hints, like seeing Ventus protest that Aqua must decline her promise date with Zack or something
How about when Sora's party came to the Chamber of Repose(? where Xemnas was frequently visiting) Aqua's armor suddenly awakens and attack Sora?Or somehow make some sort of data battles and make it the toughest fight in the game by batlting against the 3 of TAV's armor forms all at once! That would be really epic! This series need more boss fights that have multiple bosses..
