Quote - Have you tried both the morph putty tool and the morph brush?

That would have been my first thought, as I think I probably could drag the chin and jawline into the desired shape.  I just don't think it would work as well with the teeth, though (and how to affect one without affecting the other?).  They need to remain un-distorted but must still be rotated around the jaw's pivot... 

(Maybe the morph brush could use rotation as well as moving?)
