Depends my thought how it could continue:
Luffy will comeback before Kaido really take down everyone from the alliance side.
He will beat down Hybrid Kaido badly with his new power/G5, Kaido flashback will start and after that we get Awakened Kaido vs Awakened Luffy. OFC Luffy will get helps from others, like Momotaro theory is still up.
The 1on1 win against Kaido will not happen, with the Narrator of Kaido winning, Oda made it clear that Luffy lose the 1on1 fight against Kaido, he made it clear that current Kaido is the number one for a reason.
I don´t know how the endfight could end, a Momotaro team+whole strawhats like OZ+Moria fight could happen, with Luffy,Zoro,Sanji being up for the final fight. I let me surprise in that case.
For sure Awakened Kaido vs Awakened Luffy going be insane.
