I'd considered this early on for my rebreather handsets, having a hose between the case and the loop so that it would be at ambient. However I was told at a trade show by a rep that this was not a good idea as the depth is limited by the sealing gasket, not the case's structural strength. Some of the gaskets are a foam neoprene rather than solid and will compress and leak at depth regardless of the pressure difference between inside and outside.
