We're talking about 3 inches here so it won't make a lot of difference to the heeling moment. You can always not hoist the sail the last 3 inches and it will be as designed. In theory in light airs it may be beneficial to get a little higher above the boundary layer into a stronger breeze - but we're only talking 3 inches.
As to adding a healing force I'd do anything for that these days with the arthritis in my hand, back and shoulder?
