I’m well aware of that, but this is a Yonko we’re talking about here…even weakened from multiple rounds, Kaido’s still powerful enough to have knocked the strongest, most recent version of Luffy out with offpaneled ease. Might be more likely that the rubber kid pulls it off solo, but there’s plenty of reason to believe he won’t be the only other person standing at the end, and Zoro’s a candidate for obvious reasons.
