It might be doable. It would be hard to do, but doable. At some point though I think going the pneumatic route to try reduce weight on your physical tether would be the heavier option. The additional weight the tank and large piston or pistons would add in my opinion would be far more than a couple pounds of wire plus a versa planetary and chain loops.
