Probably not. The ragdoll bit is doable with the physics behavior and adding joints between the limbs with events. Before that you could use Spriter or Spine to create the controlled animations. Both have plugins I believe.
I know little about either since I'm not so much of an art guy, but presumably you'd disable that and enable the physics to cause a ragdoll effect.
Edit:
Looking at the spriter plugin it looks like you'll have to do a bit more. You can access "action points" from spriter animations so the best you can do is put a lot of those in the animation, and then when you want it to ragdoll you'd create a bunch of sprites in position of the limbs by using the action points as a guide.
