Very workable ideas, when I was younger I did just that, I had some white canvas type material that I cameoed, and would carry 3 or 4 poles ( old ski poles, or fiberglass rods, anything light) or if I could find 3 or 4 trees I would just wrap the canvas around the poles or trees and instant stand, If I thought it was a good location I would leave the stand up for a few days, if not I would take it with me
Later I purchased some very light camo material from a sporting goods store (I found duck blind material worked very well) and some plastic tie wires, I could set up in a couple of minutes, I found this picture to give you an idea of the materal I used, it is very light, and can be attached to almost anything from trees to small branches
Good Thinking Doc
