Here's a wild thought.
How about making a version of Red One camera body where you could detach the heavier part of the camera, leaving only sensor/shutter board on the lens and connecting the rest of the body with optical/power cable ?
You could make a special vest for carrying the other part of the camera, which could be put on the lower back of the camera operator, reducing the hand, shoulder and back strain and improving the weight balance of the shooters body by lowering the center of gravity. This system could also have benefits in other uses.
I'd buy that upgrade for sure.
