Well, if you're willing to pay 50% extra, it can be done for a slot with the wrong affinity or as an extra ability on an existing item. Going by how Jack handled my combo Ring of Evasion/Sustenance, though, we'd have to find a druid with Barkskin to help if I did it with your Amulet of Natural Armor. He might agree to waiving that requirement if we charge the 50% extra on the constitution bonus even though it's the more expensive ability, though.

For trying other slots, a cloak, cape, or mantle shares the protection affinity with amulets and an Amulet of Health certainly does not fall under the other affinity of amulets, discernment, so it's a no-brainer that the affinity matches there. If you have a Cloak of Resistance, I could enhance that no problem, I satisfy the Resistance requirement as well as Bear's Endurance. If not, I'm sure we could commission something that would fit both a small dragon and a kobold without much trouble. If a paladin can swing a big sword in melee without being hampered by a cloak of charisma, it's not much of a stretch, if any, to imagine a cloak that doesn't get in the way of a dragon's wings.
