My jib sock has lace lines that do the same thing as a halyard wrapped diagonally. I have used stitched on sunscreens. Besides for the obvious weight problem just exactly where you don''t want weight, they also stretch differently than the sail cloth and so really distort the airflow at the leech. In heavy air it is very hard to elimate the serious leech flutter that results from this distorted air flow without a seriously hooke leech.
The other issue is with 14 headsails, 10 of which are jibs, it would be extremely expensive to put sunshades on each of them. ;^)
