I was considering a similar project.. but I decided that if I wanted a panoramic effect there were many better options.
A 6x9 back offers the convenience of rollfilm, the option to crop less or more of the panorama, and an overall larger negative, which i find easier to work with even if i am not concerned with grain.

For lens testing, I made a 35mm adapter for my view camera by attaching an extention tube onto a wood back i made. Using an SLR to focus with really was nice.
