I am not sure this would make it safer. Hard, round helmets cause most of the force to be deflected and not absorbed. The absorbtion takes place inside the helmet. Ohio State, back in the early 60's, had a helmet with a soft pad on the outside which ran down the middle from front to back. I asked a college trainer what he thought about it and he thought it absorbed the force rather than deflected it. Those helmets didn't last long.
