Monster classes would work but don't allow multiclassing. Savage progressions allow multiclassing, but I don't see any full BAB ones.

Edit: There's also the Dwarf, Half Dragon, Half Orc, and Orc racial paragon classes, which can be taken at level 1, so that brings it up to 14, I guess. There's also Generic Warrior, but that explicitly isn't meant to be used with the rest.

Edit 2: If you count OA and CW Samurai as different classes, that would give 15, but I'm not sure this works by RAW.
Don't forget Generic Warrior, as well.
