You might find Andrew Davidhazy's articles interesting:
He is a professor at Rochester Institute of Technology and sort of specializes in making panoramic and strip cameras out of odds and ends. He also explains some of the required mathematical relationships in the design of a panoramic camera.
I agree that you don't need at RB -- any sort of folder - or just a busted film holder and a cardboard box to hold the lens - would be enough.
I wonder if you couldn't do something with a Speed Graphic. In strip camera, the slit stays put and the film moves, in the Speed's shutter, the slit moves and the film stays put. One issue is that the slit moves across its path in like a 1/5 of a second; you'd have to alter the speed and synchronize with the movement of the camera.
