Well Bryan,
simple answer, ,do a test panel, finish a test panel exactly like you propose to finish your plane, then you can answer your own question without risking your plane. My pat answer is no, dont mix product, dont mix paint types, dont mix thinners. However, you can get away with lots of stuff as proven by people with their magic systems. I personally dont see any advantage to using catalyzed primer,, then dope, then catalyzed clear. you are putting a product that will at best have marginal adhesion between two products that have great adhesion. I would say to use a standard base color system that is made for using with the primer and clear coats. It will reduce your risk of problems, and enhance the overall finish of your labored over model.
Ask Randy Powell, hes tried just about every combination out there I think,, and he is very willing to share his escapades and nightmares.
bottom line, if you want to go off the safe path, do a test panel exactly like you will do your plane, then you can be about 85 percent sure you know how it will react
