I think the answer is yes (assuming I am reading the question correctly).
I interpreted your original problem as trying to adhere an exposed
gelatin carbon tissue to mylar (instead of paper or other base
material) and then developing it on the mylar. That, at least was what
I was doing in my description above. I would occasionally get frilling
and edges peeling off, but generally, the adhesion was good, and once
the developed pigment/gelatin was dry, it was a hard and not easily
removed layer. As I said, this was with commercially prepared gravure
resist and carbon tissue, so I have no idea what effect the materials
used in "home brew" tissue might have.
Please let me know if I haven't understood or answered your question yet.
