We’re not getting 3 chapters of Kaido fighting awakened. Every time a trump card is revealed its quickly washed away like

I personally think if it happens, 3-4 chapters left is appropriate, but only if it's structured in a way that makes sense:
- 1046- has his small flashback and possibly a tease of it. Maybe by the end he transforms
- 1047- they fight on equal footing, but it's mostly a Kaido awakened showcase.
- 1048- Luffy keeps losing strength but the heartbeat keeps bringing him back, showing the brutality/fatigue of the fight overall
- 1049- Climactic vs Chapter, Luffy wins with the final hit here.
You can essentially combine 1047/1048 if it goes this way too. Or Oda does the opposite and elongates it because of ther scenes outside of the fight (everyone being rescued from the burning castle, Orochi, Denjiro, etc).
But yeah, if he does it, it probably won't be painfully long. I'd prefer a Vs Katakuri type fight if anything. Short, super intense, and it ends dramatically.
