Let bet just for fun, the battle will continue after the Onigashima raid, right now their are still to much plotholes in this one who should first check out before Kaido gonna get defeated.
-Marco and the Whitebeard pirates cannot help as long as Weevil is pursue them and Weevil want to meet/attack Luffy
-Nekomamushi isn´t back right now and we don´t know what happen to him, he should be already in this country yet he isn´t their which could mean that something happen to him(Weevil).
-Navy didn´t still come for help, they have already big problems with the Shichibukai and also they probably wait for something, without the help of the Navy, their is a no way that Kaido&Big mom alliance gonna get defeated...
-Basil make a forecast that the Strawhats probably stay in Wano for one month, at least one hint
-Based on the Kabanuki japenese theater, the hereos didn´t still get their tragedy role for act3, their isn´t any comeback for the heroes if they didn´t lose something in act3.
Based on this all, it would make more sense if the raid for Onigashima fail(but suddely they get saved from someone/any group) and the war continue all over the wano country for another 2weeks. In that time, Luffy can finish off Weevil and get the Whitebeard pirates as help, other alliance member have the time to training even more.

All of this wild cards will probably appear during the raid, can't see it going in another way.
