Despite being weakest I think nami actually has potential against the gas gas no mi, Nami has shown with her mily road that she can overcome the limitations of air pressure. If she can drop it to allow for clouds to form, maybe can increase as well. Gas+Massive Pressure=Solid.

Plus considerring she's spent two years in the sky you'd think that she's used to less oxygen then the others.
