I think a way to get around the quickchange thing is to say it's just a glamour that they put on and take off whenever they need to. Like, for instance they could make armor look like regular clothes and vice versa. It would be just like the game mechanic, except you can activate or deactivate the crystal when you need to. Obviously, it would still remain the original it would just look different. It's really not any more useful than walking off stage, but I guess people like that kind of flavor?
That being said, if you have a standard, people should respect that standard. Especially if they're very clearly posted.
