I don't know if this will be helpful to you.
I had to print a reverse image of my image. I had a negative (normal negative) and I wanted to end up with a negative image, not the usual positive. The way I achieved this is that I set my original negative on a light box and shot a macro shot of the negative onto a negative, which end up being a positive. Then I printed this positive onto a regular paper which ended up being a negative. The only thing I had to be mindful of was the contrast. I had to bump up one grade to get a normal looking image.
Here's the result:
You could potentially do the same thing and meet your gentleman's standard of method and material without using somewhat exotic paper and mind numbing printing process.
By the way, my example comes from a 35mm neg being copied to 35mm neg. Enlarged to 7x10ish size, I saw no loss of detail that my eyes can detect.
