Hate to say it, this is a really terrible idea. It's the worst of both worlds. Not only do you deal with the increased shutter+mirror shake of a 6x4.5 compared to a 35mm, he said he wanted a 28mm or 35mm wide, and 30mm's as wide as MF gets even if you're willing to mess with a fisheye (35mm otherwise). After all that, you only get a 35mm negative to boot.
