You have role-swap AUs. But what if it just happens one day everything becomes chaos? Like as in only certain factors change and not everything about that certain hermit, so it becomes a mess. 

Ex.: Ren is a werewolf or dog hybrid or something half the time, what if the normal animal hybrid role goes to someone else but it's A. a different animal or B. someone just starts acting like one. 

They don't get fully switched. It would also be funny if the switches aren't only two-wayed. Ex.: Grian gets the ability to do Redstone from Mumbo, but also the laid-back attitude of Hypno. Then Maybe Hyno on the other hand becomes more sneaky like Etho but doesn't get Grian's energetic-ness. 

I don't know if this is a good example of what I'm thinking or not. This is very much unfinished and nowhere near enough info and stuff for mt to make a part one so feel free to steal it.
