Gloss overtop Matte Coating?

I'm wrapping up a project and I had an idea to mix matte with glossy elements. I've got a spray can of Testors Spray Dullcote and then was wanting to paint the glossy elements by hand with a different gloss coating/finish. How well would those interact with each other? I'd obviously let the matte finish dry first, but would the matte "cancel" out the glossy effect or does it have some other interactions that basically make it not worth pursuing?
