I personally think they will FAIL miserably.... ALL OF THEM.... forced to retreat AWAAAY from Onigashima as the capital in middle of Wano...
Will have also a CHANGE in commander from Kaido's squad in that period because it was hinted at.... Luffy/Zoro on verge of death from Hawkins prediction in both (beginning of arc about their survival, and from his words to Drake)
And then we will have a 2nd raid.... and they win...
I truly don't believe they will win... and I do not mean that they will lose just a round and then get back up and win... no I mean it will be flat out LOSS... retreat, regroup, regather the allies, and also NEW BACK UP shows up... stand on their feet, and raid again and win...
I think act 3 and 4 will be just that damn long.
