IMO, even tough you can used tanned leather for a backing I don't think it's a good idea. Tanned leather would soak up extra glue making it heavier(physically) and will attract moisture. Put a drop of water on a piece of that leather and see how quickly it absorbs the water.
Deer or goat rawhide are both excellent for backing because they are thin and strong.
