Survivor severance

I had this idea pop up in my head while watching survivor. If severance had a survivor type show, how do you think it will work?

1) Severed vs unsevered The severed people are going as their innies (this will most likely be their first experience or it will be the ORTBO where they’ll just suddenly wake up on the island).

While the unsevered people will have an advantage because of experience. I am curious how the innies would do.

2) severed team vs severed team

3) They play against themselves

They will do the same challenge twice, but one as their outies and one as their innies. Whichever team does the fastest gets immunity. If your outie gets voted out, your innie is still in and vice versa.
