You could do the same thing Superman did to him in JLU.
Marvel was holding him up and shouting Shazam! (Magic word!) to zap Supes when Supes switched them, turning him back to Billy (the kid) and just holding a hand over his mouth so he couldn't turn back.
Do a variant of that and everybody will be happy :D
If they're not, I'll send more hammy superheroes at them!![]()
