If you take the rack apart, you really don't actually need to completely remove the piston. Removing the seal and/or drilling some holes through the piston face is more than plenty to allow effortless manual steering. Often, the energy spent removing the piston is energy wasted because the 'problem' can be 'fixed' so easily in other ways.
Once you've looped the lines at the piston, you can simply add plastic caps to the lines at the rotary valve, as there is no pressure differential inside the rotary valve without fluid moving through it. If you feel safer, some threaded plugs or even the original lines pinched off will work fine, also.

lol, yeah having an airspring in your power steering by capping off w/o piston mod/removal would not be a fun experience. Thanks for noting that.
Though you don't need to remove the piston and can just "unseal" it, I'd still recommend removing it. You are that far, it doesn't take but a few minutes to cut and chisel it out at that point. If you lack the tools, though, I can see your point.
