My theory on the Green Bit fight:

Law told Smoker they'd be heading to Green Bit. Smoker told Akainu and he dispatched Fujitora.

Law told Doflamingo to pick up Caesar at Green Bit.

My guess is that Fujitora ends up fighting Doflamingo, since he is now a regular vulnerable pirate, and that Law can do whatever he wants on Dressrosa as long as DD is away.
