Zactly - that's the whole premise of theoretical super-deep dive suits where the diver could "breathe" an oxygen-carrying liquid (perfluorocarbon-based). The theory is that the liquid (incompressible) inside a suit (which the diver could also breathe) would help to equalize the pressure inside and outside, giving much better resistance to crushing. I've no idea where the research is on that - just that it's something that was being looked at about 15-20 years ago with implications for super-deep diving and high-G load suits. Crazy stuff.
