Oh wow. That's hilarious. My answer:
Vivi should definately remain in FFIX because he just makes that game. FF9 wouldn't be half as good without him in it - his storyline is the ultimate loss of innocence and with all the relatively deformed characters running around, he's just so gosh darn cute. And although Lulu wasn't that great of a fighter, she was an awesome character given FFX's storyline. Give her a break.
