Have two characters see different versions of themselves?

I’m trying to create a project right now where a character can see themselves as something else in another person’s “home.” One player would be the guest, and the owner can change the incoming player to look like whatever they want. The guest would be able to see themselves in a mirror, but they wouldn’t know they looked different until they looked in the mirror. Can I somehow set it up so that certain cameras/planar reflections/render targets see specific models?
