I suggested this for the 360 version a few times but I'm hoping it works out for the new version. They already have skin packs for Marvel characters and they're going to release Doctor Who skin packs, why not these?
With one more season left, it would be better to wait until everything is said and done. For example, Korra's getting a new look for Book 4. There will also be plenty of new characters.
I support Skin pack 7 and 8 as long as 1 member from Daft Punk comes in each skin pack.
