Hey gang, figured I'd ask in here.

For characters like this one:

I see that the creator hasn't added bone rigging for the face, and that it is was created pre cc.  What is the best way to either rig it up, or is it possible to just swap it with a head from character creator?  the goal is to have this character's body do some talking with either the existing face, a face I created in cc, or perhaps ever a face I got from another avatar.  

Thanks in advance for any assistance.  So far this is a fantastic product.
