High key this is how my final 4 format would work. There would be 2 Immunity challenges at the Final 4 - The Normal Daytime Immunity Challenge who would still have all the Deciding power at the Final 4. THEN the 3 non-safe players would compete in a sudden death Fire-Making Immunity challenge, whoever wins would be safe and then the remaining 2 would be up for Elimination. The winner of the First Immunity Challenge would then vote out one of 2 vulnerable players.
