Why not just do the prosleeper thing, and use the fitted sheet like a sleeping bag? Let the elastic bits coremoved you snugly by pulling the left and right sides over each other. You could put the pillow outside of the coremoved, and have the elastic bit on your neck if you like a little scratch on it at night, but I prefer the pillow to be pulled lightly into the back of my head for ultimate sheet snuggles.
