Hey you know what, Laurie, try this, it might work.
I'm attaching a file of Antonia's head with only the lips showing. The vertices are still there for the head, but there are no polygons. You can morph the lips and save out an OBJ file 'as morph target" and apply it to Antonia's real head. in theory, that is. I did a simple test and it seemed to work.
The attachment is labeled with a .txt file, needs to be renamed to.obj
