If I put an actual DLC file on removable storage, could Le Fluffie work with it? I really wanna fix a “HIM” DLC track so it sorts correctly with the “H.I.M.” song on the RB3 disc. Theoretically I’d lose the ability to play it online or in Blitz, and I’d be okay with that. But is it possible?

Also, beyond the technical aspects– I’d want to know if modifying official DLC could cause some sort of problem with your Xbox Live profile or anything like that, before I proceed.
