Before the Cameramakers list re-located to Yahoo, there were some folks there who had experimented with x-ray film for optical photography. Re-organized list seems to be missing those people.
There is a very comical guy on the LF mailing list that uses X-Ray film for an ULF Shen Hao he bought in China. He goes by the name of Uncle Dick, he is very helpful and I am sure we would share his experiences with using this film.
Have not seen any recent posts, but as soon as I do I will forward you his email address.
Some (but maybe not all) x-ray films are double-sided. A lot of pinhole photographers were using x-ray film in the 80s and 90s when Freestyle had it cheap. Being double sided, it probably isn't as sharp as "normal" films, but otherwise, works fine. Further, the stuff I used had rounded corners, and a blue cast to the base. One of these days I'll get back to my pinhole work with my stocks of x-ray and aerial roll films.

Isn't X-ray film coated on both sides of the sheet?
