I'm thinking if this was connected to the boom head; it would work?

What would be the end goal of that whole system? Adjustable out haul, maybe. Adjustable down haul, not so much. Its just not that hard to come to shore and tune your sail.

All my rigs have had adjustable downhauls for decades.

KISS!

In-flight adjustable downhauls are routinely used in longboard racing, and also were standard for RS-X racing IIRC. In these classes, you are usually limited to one or two sails in the 8-9.5 m range in 6-30 knots of wind.

Outside of racing (or training for racing), adjustable downhauls are almost never used. Some windsurfers on speed or slalom gear routinely use in-flight adjustable outhauls, but the range they use a given sail is generally much smaller than in longboard racing, so there is no need for an adjustable downhaul.

Duotone XT extensions have been around forever, and while not adjustable on-the-fly, it's very easy to adjust downhaul on the water which I have found more convenient than coming in to retune. There's a Utube video of a guy totally OP'd out in the water, flails about for a bit, cranks on the XT extension, sails back. That is the main reason I like them, although rigging ease is nice (but on the beach I actually prefer a rig winch).

In-flight adjustable downhaul are certainly useful. They're just too much of a pain to setup and there's more to go wrong. So, really only used for racing where the PITA factor becomes worth while.

I have seen IQ-foil sailors (who were former RS-X sailors) use their adjustable downhauls during training. Obviously, they would not be allowed in one-design IQ-foil racing.

Oh, and in the sailboat world, I learned from watching the last AC that this is called a Cunningham:

racers that abuse their on the fly down hauls end up breaking their battens at the cambers. RSX battens ain't cheap.

the utility of getting an extra 1 to 1.5 cm of down haul is't worth the risk of having a system in place that allows a sailor to abuse it, and break batten tips.
cam sails without enough tension, end up with broken battens.

not worth it for a recreational sailor.
