I want to make an American Idol-style singing competition featuring Final Fantasy characters, but I need help with it.

I need 24 semi-finalists: 12 males and 12 females, to form a top 12 group made up of 6 males and 6 females.

Here are the semi-finalists I have chosen so far:
Males: Cecil, Locke, Cloud, Squall, Zidane, and Tidus
Females: Rosa, Celes, Tifa, Rinoa, Garnet, and Yuna

I need 6 more males and 6 more females. And please tell me the games in which the characters originated.

To make the game faster-paced, I will shorten the semi-finals to just one round, cutting 6 and 6 to form the final 12, and then eliminate two singers (one male and one female) per finalist round (similar in format to So You Think You Can Dance)

Also, I need a host (similar in style to Ryan Seacrest) and three judges (I will not include a Kara DioGuardi counterpart; I only want counterparts for Simon Cowell, Paula Abdul, and Randy Jackson).

Also, in what sub-forum should I put the game in? Please help, thank you!
