While we're discussing modifications, I'd like an LCD near the film plane for masking purposes. With pixels just out-of-focus. Calibrating registration would be annoying but once done, you could make up a mask digitally from a scan and save the hours spent doing that traditionally and end up with a totally analogue end-product. As long as you don't need a high-res mask; it'd be ok for replacing dodges, burns, SCIM masks and the like.

In fact, sounds like a plan...
