I had this idea when I was changing my back tire. Couldn't you use a turnbuckle with eyelets that fit over the shock bushings and raise and lower the wheel to wherever you want it with a wrench?
Done something like that. I shortened a cheep winch type hold down strap to do that. This works great for hiking up the swing arm. A turnbuckle would be slow. I also made a holder from 1.5" wide aluminum strapping. A picture is worth a thousand words.
