How to apply bullet impact force to animated ragdoll

I have an animated character, with ragdoll RogidBody parts that are kinematic when it's animated.
When I hit it with a bullet, I disable the animator and turn the RigidBody part to dynamic so that ragdoll behaves naturally.
But I also want the force from the bullet impact to apply to the ragdoll.
How do I do that? Since when the original bullet-ragdoll happens, the character is still animated and isn't impacted by the bullet force, and when I turn off the animation the force from the impact has already been "lost".

 

Did you try to capsule raycast around character and when bullet get to it turn on ragdoll? Or raycast in front of a bullet and turn on ragdoll when bullet raycast get to the player?
