The spoilers today about the scabbards not being strong enough to scar Kaido kind of feels like set up for someone to do it and why not Zoro if he has Enma and seems to be training his armament
Yes, Zoro is the man for the job.
However, from a storytelling perspective, it still needs to be a hard fight so Zoro and Kaido will either face off in situations benefiting Kaido or Zoro will face him at the very end. The situation benefiting Kaido is 1vs1 where he dominates and if he has the club to block the swords.
If the Supernovas gang up on him and Zoro has the opportunity to land a clean slice, that should be the end of Kaido so I guess Oda will somehow avoid that either by making Zoro join later, which means King will keep him busy until then, or Kaido will be blocking Zoro while other Supernovas are landing clean hits since they do less damage than Zoro.
