Coming from my experience with auto transport and the massive use of hydraulics, you're going to need more than that.
Hydraulic cylinders are dual flow, one line pushes fluid into the bottom of the "tube" to extend the rod, the other line fills the tube from the top and pushes the rod down to compress the internal rod. The truck i was using at work was one of 2 ever built, and they had simplified the hydraulic system as much as possible, for user convenience. We still had over 100 gallons of Hydraulic fluid in the system at any given time.
The pump unit your looking at will push the slides out but never pull them in. That's a gravity release unit, while great for a dump trailer or a snow plow that just needs on direction of pressure not useful for horizontal slides.
While i don't have slides on my 96, if i were to fathom a guess, one with slides would have an electric motor driven PTO pump. using sophisticated computerized programming to take human error out of the equation. That said, remaking the system in a manual fashion could be achieved with say, a valve bank in one of the bays, thereby eliminating the "brains" of the operation.
Prepare yourself for some amazing artwork...
Hopefully you can make sense of my artistry.
With a valve bank and hydraulic slides this could be achieved but it would have to have the equalizer blocks on the "push" to make sure the slides stay straight. A simple T would work on the return lines.
This would be a start, you would still need a second person to make sure things are level/ plumb, and when to stop since you wouldn't be able to see inside the coach while outside running valves.
You would also need lock pins as this style of system will eventually "blead down" and cause the floors so sink. You could use some anti fall hydraulic locks to solve that but that gets complicated as well.
Now that I've covered all of that don't forget to think about the age of the hydraulic lines and be prepared to replace them all. As well as all the added weight from this system.
While i like your thinking Jack bypassing the brain isn't a simple task.
