Aloha Kajgyr,
I thought I would take the chance to weigh in on how I solved this problem. I too was faced with this same dilemma a couple years ago. How to handle paddling in a headwind, and more specifically how to handle paddling safely in unpredictable wind conditions in the open ocean. Living in South Maui one of my favorite things to do is whale watching from kayaks. About three years ago I purchased my first SUP board and was instantly hooked. First chance I got I paddled out and started whale watching. The experience was exhilarating, the smaller vessel and the standing position really added a new dimension that was totally missing in the kayak. However, I soon came to learn how limited the SUP board was compared to the kayak. Conditions that were totally manageable in the kayak were exhausting and becoming potentially unsafe on the SUP. For one, following whales doesn't lend itself well to what I call the "rule of the wind", which is to say that you must always paddle a SUP in the upwind direction on the outbound leg of your journey. Being caught downwind of your launch is only made worse the farther you are from shore when the wind comes up. This is a hard learned lesson that I paid for several times before I came up with my solution.
What I ended up doing is a lot more like the conclusions you made in your first video. A double bladed paddle will do a lot more work with less effort than a single bladed paddle. Not only do you get the benefit of the lower body position and reduced wind profile, you get improved balance due to the double blade not crossing over as well as the increased cadence and power of two blades. Being totally satisfied with my carbon SUP paddle I was intent on solving this problem, but with several criteria. First, it had to be able to be used with existing SUP paddles. I didn't see the need to re-make an entire SUP paddle. Second, it had to be integral to the paddle. I didn't want to stow a paddle blade on the board or on my person. In addition, stopping to spend more than one second re-configuring the paddle was not an option. Last, it had to be easily removable without damaging the SUP paddle or requiring permanent modification. It was important that it be an accessory to the paddle and be able to be removed quickly and easily if not needed for the situation or conditions.
After messing around with a variety of designs I settled on a rotating mountable reinforced carbon fiber blade. Designed to mount on the handle end of the shaft, our design, dubbed the "Maui Blade" conforms to all the criteria listed above. It mounts via a set of custom machined Delrin nylon clamps, it can be removed with an Allen wrench and just two bolts, in under a thirty seconds. It has a specially designed, precision machined, patented rotating mount that allows the blade to rotate a full 360 degrees about the handle. Extending the blade outward from the handle for double bladed paddling or downward for standing paddling. In this way you can have a double bladed paddle for seated or kneeling paddling, or rotate the blade down and out of the way for standing paddling. Keeping the all the weight of the paddle blade below the handle allows for a very balanced paddle feel in the standing position while allowing unobstructed access to the SUP stroke.
Precision machining the rotating mount from solid billet aluminum allowed us to mount a stainless bearing and spring loaded pin lock in the rotating mechanism. The result is smooth glide that allows the blade to be rotated to either position with just an extension of the finger to push the release button and a flick of he wrist. The blade is constructed of three layers of carbon fiber reinforced by a specially designed aluminum plate molded into the blade. This makes for a lightweight yet incredibly strong and durable blade.

evokai.com/cgi-sys/suspendedpage.cgiI will say this, keep up with the ideas, don't let the detractors get to you. The dummies that jump on your thread with negative one word comments aren't worth your time. Rest assured they have never taken the risk of inventing anything of their own. You aren't the only person seeing merit with this sitting/standing, headwind safety issue and SUP, in fact there are a bunch of new boards this year that are made specifically for sitting and standing, take a look at
www.liquidlogickayaks.com/versa.cfm and
web.me.com/imaginesurf/eng/wizard.html for just two examples. This should signal that there is a lot of room left for innovation and new ideas in SUP. From my perspective I see a couple different populations of SUP paddlers. There are the people like me who are into SUP because it brings them closer to their passion, mine is whales, for others it might be fitness, fishing, or just having fun on the water. These are the people that are open to ideas like yours and mine. They are willing to try anything that makes the experience more enjoyable. And then there are those that are into SUP only because it is is SUP. They are convinced that the only way to SUP is the way they do do it, and that everyone who doesn't do it their way is either crazy or stupid. My advice is don't bother with those people, you will never change their minds, so don't waste the effort trying. There are plenty of people in the first group, probably far more than you expect. How do I know? I meet them every time I paddle, they're the people that paddle up to me and say "wow that's a great idea." I just smile and hand them my paddle and say, "here, give it a try."
