Even though the heat generated would eventually be almost negligible, it's still not going to be converted back into "pressure", neither control so effectively to which direction it would be applied.

What if it were applied to the first gif below?

The spring would probably make it go crazy in two directions instead of one.
Well, how about some conventional layouts?

These Gif's are a lot closer for discussion purposes than the bicycle diagram/video. The bike one was a "what if" the up stroke was powered. Kind of a side bar distraction, trying to stay focused.
There are a lot of stresses on conrods/rods forces from all directions, just not feeling a spring application in my bones.

The forging process ensures that the conrod is capable of high stress loads at high RPMs when the tension loads exceed 1 ton.

I'm afraid to think what a one ton spring looks like.
