Yes I would take a back up on the sleeping pad, even a light EVA pad at the minimum. There are a couple rain shells in the 9 - 10 ounce range that work well. I have a Mountain Hardware one that is decent and light.

The extra closed cell pad and a paradox can work together as a camp chair. Ask Brian Goode he has posted photos of the arrangement.
