Jerry.. While it is possible, the cost might be better spent on improving your sail slides so there is no friction to raising the sail. Most main sails can be raised by a 90 pound woman in a bikini, without a winch, if the sail and halyard are working correctly.
Over the years the mainsail track gets gunk, sand and salt in it.
To hoist the main I go to the mast, heave down on the halyard where it exits the mast, place a wedge in the organizer turning block. Then go back to the cockpit , haul up the last 50 cm and winch tight. The sail has a boltrope and it is OLD. I found that it was getting harder and harder to haul up, so I made up a track cleaner.

This is 30cm of (rough) nylon rope with a tether whipped to it. The tether ends just above the rope on one end and extends down about 5 cm or so on the lower end. The main halyard is connected to the short end (Pic 2) and a light downhaul to the other( pic 3). The rope is liberally sprayed with silicone grease then fed into the track.
I hauled up and down a couple of times. Removed it and resprayed and repeated.
It WORKS!!!! The main now glides up. Will work with slugs too. Gary
