I thought, when the SH's fought the BBP's, that Nami would team up with some, like Chopper or Ussop.
Nami & Chopper is possible but not likely. He's gonna be against Doc Q. With the attitude Doc Q has as a doctor, giving out explosive apples, he is gonna piss Chopper off like how Dr. Hogback did.
I can see a team up like how Chopper/Robin fought Hogback/Cindry/Innupe/Jigoro, but not Chopper/Nami vs one single character
As for Nami/Usopp = No, just no.
Usopp will be up against Van Auger.
In a sniper vs sniper battle a non-gun user like Nami would be in the way.
Don't forget there is a female on the BB crew= Catarina Devon, who uses a spear or staff as a weapon.
