If you bring up the parameter dials for the head, the spawned morph appears in the morph category and it is called head. If the dial is at zero set it to one to change the head shape. You should be able to save it as a morph target the usual way. File/export/wavefront object single frame and save only the head no eyes or any other parts. If you make a new scene you can load your character and test the morph. In the object menu do load morph target after selecting the head. You may have to adjust the position of the eyes. I hope this helps...
