Have you tried a lower viscosity, solvent based consolidant, or
slightly more heat and pressure with the heat spatula?  In similar
situations, I've achieved good visual and structural results with
B-72 allowed to dry overnight. A higher temperature and more
pressure with the spatula applied over a relatively thick piece of
Mylar can definitely help smooth the outline of the blister if the
coating you are consolidating allows it.
