Barry,
If you go to YouTube and google drytac you will find a video showing the process of laminating a print to mdf and then wrapping the image around the sides to the back. I will have to view the video again but am pretty sure it does not mention the paper type. It's also possible he used the hot press,not sure. I would try laminating some of your favorite papers first,then see if they can be folded around the sides and backs retaining their flexibility without cracking the paper fibers.
Your about a week ahead of me as I will be pretty much doing my own tests.
