A brain inside a body moving at 17 MPH will continue to move at 17 MPH when the body rapidly decelerates to 0 MPH causing it to smash into the inside of your skull. Your brain is like a person driving down the highway in a car without a seat belt. When the car hits a wall the person gets ejected through the windshield into said wall, your brain does the same thing into the inside of your skull. It doesn't matter how good we make the exteriors of the car in absorbing the force (helmets), you are still going through that windshield without a seat belt on.
Now the reason the target area changes matter is because a shot to the head multiplies that force in the opposite direction. If a guy gets hit in the head the momentum of their skull is redirected back towards the brain which is still traveling at that same 17 MPH. This creates even more force when the brain impacts the skull versus getting hit in the waist and your body and neck slightly allowing for deceleration, think of this as cars being built to collapse to try to decelerate.
What you are saying is largely accurate, but if you don't have a study comparing TWO concussion cap helmets hitting with the same force of non-concussion cap helments, what you are saying is just your opinion. The half-inch pad around the helmet hitting the half inch pad on the other helmet would have a substantially greater reduction on the trauma of the brain.
To use your automotive analogy, I remember when the third generation Camaro and Firebird were being designed. It became apparent to the engineers that having glass all the way over the top of the dash was actually safer (and this was proven by crash test dummies with sensors) than the steel roof edge. Why? The head of dummies (without belts or airbags) would not decelerate as quickly when it hit safety glass because it was partially fracture the glass and go slightly in to the windsheild, without going through it.
The extra inch between two helmets would absolutely "soften the blow".
