I think there is a chance of this happening(at least something similar). Kaido pretty much is setting up the stage in wano with audience, and they might get to see Ryuuma 2.0.
Zoro didn't take down: Crocodile, Enel, Lucci, Kuma, Doflamingo
Zoro attacked: mildly roided Hody (and still didn't take him down, nor even fight him in his final form)
Not looking good for ZKK.
Luffy has claimed him, and this arc is centred around 10 years of real time of Luffy challenging the yonko and let me remind you Luffy is the main character...
Ryuma killed a western dragon not an eastern dragon like kaido.
Zoro is simultaneously the best inheritor of Oden's will due to Enma, but also the greatest inheritor of Ryuma despite giving back Shusui back to Wano.
In truth he is closer to Ryuma as a direct relative of his, but he carrys his own will.
Momo (and Luffy as his direct ally) are far more alligned with carrying Oden's will in this fight, and that is ok.
