Drake is not gonna fight against the pirates probably and assuming Perospero will replace him, he would massacre Chopper, 0% chance for him.
And Nami can't fight anyone there if Zeus is not with her.
Usopp best feat was oneshoting a fighter fish in DR...
Nop, there's no way this will happen.
These Strawhats will fight more probably against some Numbers (Tobi Roppo > Numbers). A Giant Chopper vs a true Giant, Franky Shogun vs another Giant, Robin Giants hands vs a Giant (though Robin could hold Hakuba, so maybe she will fight a Tobi Roppo, or even Jack in team with Jinbei, for example), Usopp with Giants Plants vs a Giant.
