Hi Einstein.
The following few messages are from a thread on a different forum form 2006. I was playing with the idea of a one wheel cart that could fold up into a pack frame so you could carry it all as a pack if you had to. My weight was at 3 but I that weight to drop. The big factor was a light weight – cheap wheel. I found several light wheels but they cost a lot. The cart would have been mostly titanium and carbon fiber.

I have thought about something like this for trails where they let Mt Bikes. Some of the Colorado Trail (CT) is open to Mt Bikes. I have thought about using something like this for an unsupported/non-resupplied CT hike. If the wheel sled was made in a way that it could become a pack frame (see my Sled/Pack Thread here someplace) it could be used on a lot of trails. It would have to be light say in the 3 pound range complete.
Could be done.

That is an interesting idea but did you check the weight? It lists a weight of 4.2 Kg (9.26 pounds) plus the wheel weight of 1.1Kg (2.43 pounds). In my world of Super Ultra Light gear that (total of 11.69 pounds) is really heavy.
With a lighter pack/load weight the wheel/sled thing could be made out of very light but strong material and with a weight goal of 3 pounds or less.
Finding the right parts such as a smallish light weight wheel would be the key to the overall weight. Building the frame and the rest of the wheel/sled would be the easy part.
If I could find the right wheel I would make something like this to play with.

A local dealer could get that wheel and said it would cost about $240. He will contact Dahon on Monday and see how much that wheel weighs. When told what the idea was he said he would look for some other options. Dahon has a bike trailer called the "Carry Freedom Trailer" that has two smaller wheels that also might be worth a look at. http://www.dahon.com/b-carryfreedom.htm

I just came back from a local bike shop. Three ways to get a light wheel/just a wheel.
1- Build from scratch with a 20" aluminum rim, hub W/Ti quick release, 32 spokes and a tire w/tube about 2.5 pounds and about $240.00.
2 – Buy a complete 20" "AreoSpoke Al / Carbon Fiber 5 spoke wheel, Hub w/Ti quick release, Tire w/tube about 2.5 pounds and about $284.00.
The tire w/tube would be the same for both wheels and $40 might be a little high and is an estimate. There are a lot of different tires to pick from. The AreoSpoke wheel would be less problems I think than one with spokes.
It the wheel was one of these or another one about like them 2.5 pounds for the wheel/tire etc might be a good weight for planning.
My 3 pound weigh (estimate for a weight goal) might need to move to under 4 pounds for the wheel/sled/pack/trailor thing.
3 – Aways a third option. Find a used 20" front wheel, tune it up and give it a new tire and tube if necessary and maybe spend $50. Save a few bucks but add a little weight and end up with a wheel that might weigh 3 or 4 pounds.
