I personally would be all for this as long as they try to keep entire show cuts to a minimum and bring back cut characters from the previous game on occasion. Absolutely seems most realistic. I think the show selection as of now is a decent one to keep as final - while I have developed some gripes with the NASB2 roster now the cutchud panic is mostly over (particularly 2000s overrep, but even then I don't blame that on the cuts or any individual characters) I think they had the right idea of "add 2 or so shows, focus on the side casts of the shows we have", there are ChalkZones and Fanboy & Chum Chums to be added, but I think digging deeper into the sidekicks, villains, rivals, and comic-reliefs should take priority.
