As a player and a co-GM, I will start out with saying I am [i]really[/i] not a fan of any challenges that involve transforming or swapping characters.

This is largely because I generally feel like people have signed up to play a character, with that character's personality, appearance, and powers all intact. This is how I feel about it at least.

That being said, the non-transforming ones have potential, though I'll have to look into them a bit more.

Hm.  Well, you're the boss.  Or co-boss.

One Of Us seems tough to manage because it would be totally arbitrary or powergamed whether anyone ever found the real person.

You're right, people who have characters in the same area would have to think about how it would play out beforehand.  That's reaching suspiciously into collab territory though, so perhaps it's just not a good idea.
