Would make sense.
Phase 1: Luffy, Kid, Law, Zoro, Killer -> Luffy self-knockout cause overusing Haki/G4
Break 1: Zoro, Kid, Law, Killer hold Kaido for a few minutes till knocked out or blitzed
Phase 2: Luffy, Kid, Law -> Luffy get knockouted by Kaido
Break 2: Kid holds Kaido till Luffy gets healed by Marco
Phase 3: Final Fight Luffy vs Kaido
