I'm sending my players to a demiplane of madness inspired by Xoriat. Tips?

In fact it would be really funny just to do a nice old fashioned mind swap. All the same characters but with each other's bodies.

I... really like this, actually. Should I make them trade character sheets or just apply the physical changes?

The monsters thing sounds cool too, but it would be really hard to pull off. Same with the shifting maze.
