I mostly wanted Kevin to say "gadzooks," but the more I considered my magic system... Yeah.
People being able to mimic others wouldn't necessarily be some rare thing.
Some people would be able to do it better than others, and it's not really an argument that renders the dangers of having clone forms lying around a moot point, but it would potentially be as common as awakened magic users with genuine desire for such abilities.
Ultimately, though, what matters is this:
Kevin got to say "gadzooks."
