I think your plan will work. You will need to devise a "gin" pole and a way to keep the mast from swaying side-to-side while raising (or lowering). The side-sway is usually controlled using "baby stays" which are temporary lines from someplace on the toe rail to a point about halfway between the deck and the spreaders. I have used ratchet straps for this purpose with very good results on a Balboa 26.
For the gin pole... you need a way to put the pole about 6" from the mast foot and then secure the base of the gin pole to the mast. I have see people cut a "Y" out of 1" boards and screw it to a 2"x4" and then using eye straps, tied the "Y" in place so it won't slip during a lift.
You then tie the jib halyard to the top of the gin pole. A lifting line then goes from the top of the gin pole to a strong block near the bow. Then lead this back to the cockpit winch.
