Interesting idea........
I believe the optical resolution of the larger X-ray scanners is in the 300-600 dpi range. This may be sufficient for your application. Density is good for the files I've seen, but that is now quite a few years back. Most of these scanners work by pulling the sheet over a stationary line array, at least, the ones I've seen. As for flatbed scanners, the largest one I played with is 12.2" x 17.2". Anything larger are low resolution document scanners, up to a few feet wide and poor Dmax ...
somthing like this:

* Laser film digitizer capable of digitizing films up to 14"x17" in size
* Precision instrument designed to scan film and directly measure optical density over a wide dynamic range with a high-signal to noise ratio
* Spot of light derived Helium-Neon laser is scanned across film plane as film is moved perpendicular to laser scan
* Can digitize up to 4096 pixels over a film width of 14"
* Light collection system permits collection angles of over 150º degrees at each point
Yep ... quite a few of these around ... but not even 300 dpi ...
