...-_-; In KH there was no one from FF9 or any of the FFs below 7 because Nomura didn't make those characters, Amano did, so unless Amano works on KH2, I highly doubt seeing any FF9 characters/bosses or any FF6 and below characters and bosses. Thank you. Personally, I think Ultimecia would do well, and Ultima/Omega Weapon since it's appeared through the series so many times.
