Here's a long shot (not DV related)

That's a great question and project, though I've never used either of those Polaroid cameras. Not sure it'd be worth going to all the effort to add a medium format back to those, plus first thing you'd want to check on both Polaroids is whether or not there's any light leak in the baffles as they can degrade over the years.

I used to use a more contemporary Polaroid ProPack for my outdoor polaroids, but eventually the film became too expensive so I dropped it years ago.
