Its tbh the only logical scenario in which Zoro would ever touch Kaido. The Oden flashback basically confirmed that enma isn't a magic yonko slaying sword. Oden did the same thing with habiriki that he did with enma. It was never Enma that gave Oden the ability to cut Kaido, it was Oden's own strength that accomplished that feat.
Zoro isn't going from high diffing Pica and getting 1 shot by Killer(whereas Luffy tanked a similar hit by katakuri and went on to fight for hours more and win) to being able to land a critical hit on kaido.
Anyways Zoro taking a beating by Kaido in order to help Luffy recover would show Zoro's insane endurance and his devotion to Luffy while giving Luffy the edge he needs to beat Kaido.

The next most logical power-up for Zoro will be AdCoA, which we know can bypass Kaido's durability, that's how he will cut him.

First you're saying that Zoro high-diffed Pica and got one-shotted by Killer, now it's to show Zoro's insane endurance.
Second you're saying that Zoro will give Luffy time to recover, but:
1. Why should Kaido even give Zoro a chance to hit him, if he will be going to kill Luffy. Why shouldn't he just momentarily one-shot him?
2. If Zoro will try to fight Kaido, how can he even take his attention if he "High-Diffed" Pica.
3. How Zoro would even survive Kaido's club if he "got one-shotted" by Killer"?
4. It would repetitive to show Zoro's devotion to Luffy, he already did it.
5. It won't show anything from Zoro's side. Just will lower him. An idiot who tried to fight The WSC, did nothing and got No-Diffed.
