So far, it all sounds quite complicated to use. I'm not sure if the few people who want to do hires morphs in Poser themselves wouldn't rather spend the 10 dollars a month (or 180 for perpetual) for ZBrush Core.

But what the heck: programmers just love it the hard way :)

I wouldn't include the whole thing in another script that doesn't directly fit the theme (hires morphs). Rather I would try to build an interface that hides the quite complex and likely error-prone process. The UI can export the figure from Poser in two or three copies as desired (including the vertex crosslist if necessary) and then feed your script with the filenames and parameters. Then the UI can take the sculpted result and assign it to the correct figure.

Each step can be accompanied with appropriate text or images in the UI.

The user just has to remember the export directory and put the result from Blender there.

Biggest hurdle for the user could be: Installing the Python interpreter with all the necessary libs....
