I actually would not mind a ceiling mounted design where the headset is counterweighted so it is essentially "floating" and you pull it down to put on your head. I know it will take away from the mobility of the headset, but I am okay with being stuck to a 6ft radius while working. It could also charge through the ceiling.

Or a bump helmet and hook the whole thing to the Night Vision Goggle mount on the front (like the new IVAS design), and put counterweights on the back to prevent it from shifting down. That could take a lot of pressure off your face and make the whole headborne system more balanced.
