Pudding didn't married, I don't understand also the point what you trying to say with that. Did that change these facts:
She literally try to kill Chiffon baby, so what is your point?
Attacking Kaido strongest force meaning to risking the alliance with Kaido. She basically helping Kaido enemy right now and I doubt BM let Tama attacked again by someone with means free room enough for her.
Tama can basically do now anything.
Without a ally Big mom not going to became a pirateking. If she would alone be enough, she would not need a alliance with Elbaf or Kaido.
Smiles get build up and hyped by Oda since punk hazard. Law and the strawhats risk their life in Dressrosa to take off the smile factory. They just need to take Tama who tame anyone now. Smile is and was important, well until Tama showing up.
It doesn't matter if Usopp or Nami now defeating Ulti and Pageond via help, Tama already outshine them. Alone with the fact that Tama is the reason that Usopp and Nami survive and Franky not getting gangbanged should tell you enough. And if Linlin really join Tama, their is no way that Usopp or Nami outshinning her in this arc.
