You're hoping for a low friction surface by using graphite powder? I would think that the surface will be 100% dictated by the mylar surface that is used as the press. I once sprayed flat black paint on a waxed mylar and layed up a wing. That yielded a glossy black wing. Indeed, exactly the same gloss as the mylar.
Be sure to give us a Mini-How-To for the wing lay up procedure. If you use epoxy as the resin you'll have lots of working time to wipe your hands (gloves) and snap a photo. Your Mini-How-To might encourage others to try this method.
