If I could Re-do X-2 I would.

1.Have more playable characters. Get Tidus back on chapter 2, joining the Gullwings with Garik and Gippal (or Nooj / Baralai) to make a 6 player team
2.Nix Brother - too annoying - leave Buddy and Shinra.
3.Nix chapters 2 and 4 entirely, trade it for more Bevelle intrigue, make New Yevon meaner and darker.
4.Keep X-2 battle system, only redeeming thing of the game
5.Shinra would be Bahamut's fayth under cover, following Yuna to keep her out of trouble
6.Keep the monster Arena

Actually Soulcalibur IV, a very "manly" battle game also has new outfits for it's characters. But they let you add new weapons and armor too. I'd just add the ability to add weapons and change the darn name - dress and garments ? too girly!!!!
