Here's where I am asking for your assistance....
When I desaturate the photo I then proceed to go to Filters/Artistic/Photocopy (legacy) then voila a small preview
Photocopy 4"X4" window pops up. This size preview is difficult to get a good visual of the whole face.
I really need a larger shot of the face to design a quality scroll saw pattern.

The short answer is you can't.  The old legacy photocopy comes from an era when images were smaller and that preview was adequate. (It is possible to increase the preview size by re-compiling the plugin but not easy)

I see the problem with the newer GEGL photocopy, nothing like the legacy version.

You might get something a little closer, all depends on the images.
(1) Desaturate as before
(2) Duplicate the layer and put the mode into divide. That gives you a blank canvas, do not worry
(3) Use the Neon edge detect filter Filters -> Edge Detect -> Neon and adjust the Intensity slider and you might get something similar to the legacy photocopy.
