Some thoughts:
The current air compressor appears to produce alot of excess air most of which is dumped by the pressure regulator compared to how much is passing through the air injectors. The air injector are tiny and only open for short period in comparison to the regulator.
Per the design of the atomizers there is a pressure that is optimal for fuel atomization. Slow down the compressor speed and you will get larger variations in air pressure.
The cam and bearing were the weak points especially in the early compressor design. You would need some advanced engineering/modeling to figure out if slowing down vs Less air compression force(smaller piston) would put smaller more stable loads on the compressor cam/bearing.

This is why I feel just using a higher quality, ceramic coated & lighter piston will prevail as the needed measure. Reducing drag, weight, load and wear to the bearings should remedy the majority of causes for the pump failure.
Every other measure would require much engineering and effort to redesign the wheel.

I agree with you. If you can reduce the weight of piston and the piston is robust enough to never fail it would only benefit the cam and bearing.
