Hi: If its any help I looked up the largest size of the ortho film I use. (Kpgraphics Kodak Camera 2000 CGP film)
Its a 52 inch by 200 foot roll. See http://www.kpgraphics.com/pdf/info/FilmAndPaperProducts.pdf If this was used, I wonder if you could skip the initial pre-wash, and make a giant vaccuum frame for to get good contact for the contact print. I've heard of people making a vaccuum frame with sheets of clear mylar, instead of glass on a wooden base. But that goes against the rule of thumb of keeping things as simple as possible ;) I'm astounded at the effort you've put into this. Once you figure out all the details we'll have to get a number of room size pinhole cameras shots on pinhole day all over the world next year and then make an international travelling exhibition with them :) Nothing like thinking big.
