Quote - I wonder if you could set it up like Real Skin Shader so that it can apply to textures already on the figure...

From a programming point of view (not that I program with Python, but in a general sense of my experience in other languages) that could make things a whole lot easer.  If there was an already applied texture that the new program could capture and use...

You'd need to set up seperate variables for head and body (and perhaps things like the eye nodes, especially the cornea?) but all in all it sounds like a promising route to try.
