Hmm... picking up Zoro, Usopp, Robin, and Franky before fighting Big Mom doesn't sound improbable by any means. However, if the current group of Straw Hats manage to get Luffy to recover first, will Sanji, Nami, Chopper, Brook, and likely Jinbe also directly help Luffy out this fight? Or will Luffy fight Linlin by himself despite knowing that she is much stronger than him? I do not think the latter option is likely in the New World.
