Something like the German mat might work for you since it folds in half and can be stuck under most straps and stay within the planes of the pack sides without sticking out to the sides like most foam mats will.
I'll scour the web and see if I can find one, its worth a shot, since it folds flat I can probably fit it inside the pack as well since it could possibly fit against the walls of front or back of the pack. And like you said, if the inflatable pad fails a little bit of insulation is better than zero
