Yes, but I'm not familiar with this topic, especially in case of Blender.
The procedure will depend on whether you still have weightmaps or not.
But even if you do have weightmaps - the main problem is the usual number of bones in humanoid skeletons.
Each bone must be reattached (in modo's term's - "bind") to corresponding weightmap.
And I never saw anything to make this automated (but I never searched thoroughly)
