You might want to consider a minimalist bivy sack (definitely under a pound) and a temperature appropriate sleeping bag so you will truly rest, combined with a thermos or two with something hot to go along with your breakfast of sweet rolls.

If the ground is too steep, look into a trekking hammock to hang from a sturdy tree or two.

Frankly, I would just get up early and walk in. If you scout and brush out the route beforehand, it would be a lot easier.
