They win. Sanji and Zoro do most of the work, Franky's Radical Beam should do good damage if she isn't paying attention and doesn't guard with Haki. Usopp, Vivi and Chopper are just in the way.
I think I'd rather Gohan and the boys be the ones to beat him since they have more potential than Goku/Vegeta. Teenage Gotenks & Gohan tag team would be a nice change up.
