If it was me...
I would go to home depot and buy a painters pole, the one that is like 18' or so. I would attach a Y bracket at the top. I would use that to push the mast up at the spreaders then use the pole as a tripod with respect to the shrouds. Then lift the base of the mast into the step, attach the headstay and adjust.
To take it down, rest the painter pole under the spreaders and reverse the process.
If this were me...
I had a 15ft Montgomery. I was able to fit a hinged base plate to the mast and the step. I would lay the mast down in the boat. Attach the hinge pin. Attach the side stays and run the jib halyard to the bow then through a pulley back to the cockpit. I would stand in the boat grabbing the mast about half way, near the balance point. I would lift the mast and pull up the slack on the jib halyard. If I had a helper I would have them pull the jib halyard while ai Lifted the mast into place. With the side stays attached when I got the mast up the stays kept it vertical. By pulling the jib halyard I was able to lift the mast top portion while I pushed and guided the rest of the mast.
Perhaps you can use a similar technique.
Post pictures of the mast step and the mast base so we can see the challenge you are facing,
This might be a need. The gin pole idea is great but you will need to modify the mast.other than ‘start lifting weights’ ?
