What would happen if I mixed positive and negative photoresists?

Without knowing what the positive developer does to the negative photoresist and vice versa, I can only guess.
Assuming the developers are just washing agents, then the positive photoresist will stay on the unexposed parts, and the negative photoresist will stay on the exposed parts. So you would get an entirely covered substrate.
Why not try the experiment you are proposing in your lab, and tell us the results? That would be neat.
