That would eliminate the complexities of filtration and exposing only one side. Of course then you'd have the registration problem when you went to put it back together. IDK.

This is exactly correct. And, the color developers would be much simpler.

Registration would not be a significant problem, as many processes used it in the past. The real problem is the thickness of 3 sheets of support which may cause some sharpness problems. IDK for sure.
