I dont know if Crazytalk is still in development but I think crazy talk 9 could be possible.

I've suggested this feature for ic8 but should be available for CC4 as well. Users can benefit with a light weight application such as crazy talk for vblogging/live streaming but you should also give users control for mixing in transition videos, live or scheduled on screen text & graphics. Crazy talk should also allow other 3D characters to be imported with a marque to select just the region of the head area to render.
