I've never used a tent footprint in 1001 nights. It protects the bottom of the tent. Since you're not carrying, you can use a polythene sheet cut to the tent's footprint.

That sleeping bag should do the job. It's even a bit too much but I've never been too hot in a bag (just unzip). Make sure there's a two-way zipper so you can vent the feet independantly. Again, if you're not carrying, you might as well use a few blankets.
