SO these new heads would need a complete set of morphs to work with them also. Actually this isn't a bad idea, and why limit it to just DAZ creating them. Essentially what you would need is the CR2 that referenced mikes OBJ file, then in the section for the head give an alternategeom so that you will have the new head. Taking this idea further, using the same technique for pose files, you can have a new alternate geom added to the figure using this I believe. At that point all the user would have to do is change the "Change Head" Dial. THis is similiar to the way the genitals are done. I'm just unsure if the new dial will show up when you import in this fashion. Biut of course durng that pose import you can have the default set to the value that would load this additional head. The only requirement is that the head has the exact same vertices where it joins the neck as the original head. Of course then you need an entirely new UVmap and texture for this head, but seeing how the mike figure already uses a separate map for this I don't think it is that much of an issue.
