My gut feel is that momentum transfer itself plays a minimal role. I tend to think that the primary contributors are, (1) the stretch contraction reflexes that kick in when abrupt movement of one link loads the next one in the chain, and (2) the torque developed by the joint. Of course, each link always "piggybacks" on the previous one, as you have aptly put it.

I only point this out because I think there is too much acceptance of the momentum transfer theory, and if people actually try to stop hip or shoulder rotation midstream to get racquet head speed, they will surely hurt themselves...
