Yes, I did see your video and I think you've got a nice prototype there.
I agree that light weight and durability are difficult to achieve in the same design. I managed to come up with a workable solution for my setup. For light weight and heat resistance, nothing beats titanium. The 0.005in. titanium from Titanium Goat is amazing stuff. With the fan on, the whole stove glows orange. At night it's a sight to behold, but it holds it's shape pretty well and shows no sign of burnout.
There is one 0.01in. stanless steel ring in the base where the legs attach and one in the base of the windscreen where it rests on the firebox. The Ti was too flexible in these horizontal areas to support the weight of a full 2 quart pot.
I've been using it since last February and it's in great shape. The secret is in the packing. everything except the windscreen packs inside the pot. The windscreen packs around the pot. So the pot protects the stove, and supports the screen so it can't be crushed in my pack. Without the pot, the paper thin stove would have been crushed on the first outing.
The fan setup pictured above puts out too much air, and after viewing your video, I'd say you could also get away with less air movement. As I write this, the JB weld is setting up on the manifold of my new fan which is much smaller and has about a third the power of my original setup. The cardboard mock-up of the new fan and duct is pictured below.
