I've actually tried this and I agree, it is very difficult to run a strip of film through two super-8 projectors at the same time. Try it——you'll see the section of film between the projectors either get short (and break) or just get super long, and yeah, your tensions gets screwed up, loops get lost, ect. I think the catch to doing it is using projectors that have variable speed knobs (like the high-end Elmos), which allow you to add, say, a an extra fps to either side as it is running. But you'd have to kind of sit there and ride the system as it's playing and not expect any kind of sync. I believe it can be done but requires a lot of practice.
tENTATIVELY, a cONVENIENCE sometimes shows work kind of like this——silent film works projected on top of their video manifestations. The videos have sound and it kind of makes sense, at least to him. So your watching two versions of the same thing, slightly out of sync, with sound that relates and kind of drifts over the screening. During the screening he'll kind of command the projectionist to slow down or speed up the projector, stop it to allow the video to catch up etc, striving for some unacheivable state of synchrony, which is of course impossible. Of course, all this participation becomes primary to the piece, as does this impossibility. This tend to be crazy situations, which might not be what you are going for. But good luck with it!
