ok, great idea. I can see the mechanical advantage in this, even if slightly over complicated.
I am 40 and rather spry for my age, but I do this whole operation single handed with my main sheet, an auto body panel stand, a ratchet strap and a bit of rope....
strap goes around the mast about 8ft up (as high as I can reach, eyeball it when mast is down) panel stand holds the mast in the cockpit slightly over center(higher than step) , mainsheet fully extended goes from bow rail to the strap on the mast ( pulling on bow rail is higher than mast, so now mast is over center slightly and we have a bit of up pull from the sheet pulling off the rail. Thus closing the angle to less than 180 degrees.) I tie a line to the end of the main sheet to extend it. I stand in the cockpit, and give the mast a boost up as I pull on the mainsheet to bring the mast up. If you do this with the boat pointing downhill it is super easy and the mast will hold it's self forward when fully up.
If you keep your step pivot bolt slightly snug it helps control side to side movement until your stays take over.
This is how I do it on my sc22 and I have stepped my Laguna 26 the same way.
While I see the advantage to your design, I don't know that it would be much more efficient. I can see how it would give greater control lowering the mast as things happen quickly going down and the mast and mainsheet angle get close to the same. Rope stretch becomes very apparent at that point.
