I've tried something similar a couple times. Once on a canoe trip where we found a great spot and just paddled back to it each day, I built a low (18") 3-sided wall next to my trench. Slept under a tarp within a foot of the fire and kept feeding it from the walls - was pretty comfy. The other time we were camping on my buddy's property and I built a lean-to. There were a couple pieces of bent sheet metal in the woods I rigged up as reflectors and then strung a mylar blanket up on the roof of the shelter. It got down to about 25f overnight and I was almost too hot. Pic related is the lean-to. Looked like shit, but tarp roof and garbage bag cut in half for sides all strung over a rickety "frame"... it worked and I had fun.
