The way I see it, Luffy has to, more or less, 1v1 Kaido.
Apart from Luffy, the only people who can even damage Kaido are Zoro, Law(gamma knife), and maybe Kid(as he could theoretically bypass Kaido's durability by using magnetism to attack the iron in his body)
Given that Big Mom is also part of this arc. The latter 3 will most likely have their hands tied and won't be able to fight Kaido for a prolonged period of time. In Zoro's case in particular, he might also have to deal with King.
While Luffy might not be on Kaido's level yet, ACoA likely put him close, with him now being able to dish out KKG casually(as shown in his udon training).
What I think it will likely be is something like dressrosa where Luffy does 90% of the damage on Kaido and everyone else just steps in and covers for him while Luffy's haki is recovering during G4. But I think the scabbards and the other supernova will just stall Kaido for Luffy, I don't think they'll actually put in work against him
