Hey, cool, something I might can contribute to. I've been known to have my sled team drag along 500 lbs of gear in mid-Winter, so I don't normally have anything to contribute here.
Here is a mockup of a Scott tent out of painter's canvas, emt conduit poles. The poles were joined at the peak with a metal ring. I sawed the ring apart, drilled holes in the end of the poles and threaded the poles onto the ring, then clamped the ring back together. The idea was to drag the tent around on a Nansen sled with the poles and tent all folded together, then set up with about a five minute setup time in very cold weather.
I never got back to the project, but I've used the tent a few times and like the setup.
Here's a shot that maybe you can see where the poles converge on the ring.
