After discussions with Ryan (TCAD and Stormscope folks) and learning of their test failures with painted ground planes, I started on a new tack.  Nickel metallized graphite fibers are used effectively for EMI shielding so I contacted a supplier to discuss.  They had no actual antenna experience but gave me a sample of the fabric to test.  We made an evaluation plaque by encorporating two veils into a carbon fiber wet layup and sent it to a field site for antenna testing.  Results were quite favorable compared to a solid Al plane so that is the route that I will travel.  I'll let the LML know how it works out in a real environment and after some time aging and undergoing repeated pressurization stresses.
