The problem is that if they defeat the Vinsmokes then they have to escape Big Mom xD. Although the possibility that I see is that Big Mom forgive Luffy and the others by Lola, or just at the wedding the Vinsmokes or the Firetank Pirates betray Linlin and Luffy stand on the side of it.

I also believe that Big Mom will not be the villain final, less with a huge army that no joke can overthrow him. In the event that Big Mom is not allied to Luffy I see a possible flight of Whole Cake Island with hands Poneglyph and Big Mom chasing after them. Even so, Big Mom is supposed to fall in some way, may not be out there especially because (presumably) does not have to be any Yonko.

Let's see what makes Oda.
