Actually, there are 13 constellations. Serpentarius is sometimes referred to as the 13th zodiac.

Straw Hats + Law + Kinemon = 11 - That would work out if some of the enemies were so weak they have to fight in a pair or don't fight at all. Or Oda extends this shit till the Reverie and lets Jinbe and Vivi join the fun.
