Response to I don't think so

then the spring could only make second stage pumping harder. Here's what I think we're talking about.

So the spring preload takes the place of the ball detents, and once the 1st-stage piston bottoms out the spring begins to compress and the second-stage piston keeps moving. The problem is that the spring can only increase the force needed to compress the second stage, and there's no way to get the energy back.
