I am interested in doing this with 4x5.
I have 4x5 E6 images and 4x5 B&W film, I'll be using the negs for contact printing alt processes. In my mind it seems pretty easy...I'm thinking all I'd need to do is sandwich the positive e6 and the B&W emulsion to base, do some test strips, and develop like normal. Has anybody out there tried this, and if so is there anything I should be aware of?
