If Kingdom Hearts becomes a movie which actors and actresses do you think would best portray Sora Kairi Riku Namine etc

This has to be the greatest question I have ever had. OK Kairi would be Hayden Panttiere here voice actress. Sora would be Haley Joel Osment you know the kid from the sixth sent only because he is Sora's voice actor. Finally Riku would be me after a Little dying of the hair.
