Do you think this is a possible route Oda could take? Imo it is possible and there are more than some hints (even if I still think Z vs King is more plausible) like Luffy, who of course is gonna fight Kaido, is training for it but at the same time Zoro is the only one among the strong ones who is getting a training program and also a direct link to Kaido in getting the sword that wound him and it could very well happen that we will arrive at a point where only L and Z have the ability to wound him. In other words it seems Kidd didn't do a scratch to him just like L in round 1 and about Law we are not even sure he can beat Doffy solo at this point let alone injure Kaido when G4 failed, anyway none of these 2 is shown to be trying to develop something that can actually go past his defense unlime L and Z.
Also if this happens imo it is not the final fight as Luffy needs to do this alone (or beat another yonko alone) while Zoro would be better in a full fight vs King, so maybe a 2nd round where both L and Z get overpowered by Kaido? Maybe Z will not be able to wound him like Oden did and so have a new goal to reach before the arc ends (and accomplish it somewhat by beating King) What do you think?
And at this point, considering the hype this sword get, the bare minim for Zoro is King, Kyoshi will at best be an appetizer, for sure not something worthy of being the final test in Wano for a Zoro with Enma (unless he is revealed to be some really big shot who can be compared to King but I doubt that).
