Not sure i follow your plan, but if it is to remove the ss trim then lift up and separate the upper and lower halves of the hardtop, I doubt you can do that.
The balsa core is glued to the fg skins and the coring is not all rotted. There are, to my experience areas of sound core next to totally rotten core, and the sound core is firmly attached to the fg skin and will prevent you from separating the upper and lower surfaces.
