It seems like a bad idea to me for two reasons.
1. If it was already more complicated to get the outfits because of the prices, now I can't imagine all the outfits separated from the characters.
2. They're going to give more costumes to characters loved by fans than to characters that are too forgotten like Edison, Zuri, Brandon, etc., or even modern characters like Lana, Darryl, Buzz, etc.
Sometimes I think SYBO does this to get more money than they already have.
