For smithing, my idea is that player smiths could upgrade armor or weapons. You could upgrade your weapon/armor up to five times, but you risk destroying the weapon/armor. The way it would work, is you choose what part of the weapon/armor you want to upgrade. Here's an example. Let's use a Rune plate, each upgrade would require 1 rune bar. You could upgrade any of the defenses up to five times, but it doesn't have to be the same defense stat. If you wanted to make your rune armor much more resistant to ranged attacks, you could upgrade the range defense five times. You could also do something like upgrading the range defense three times, and slash defense twice. Each time you upgraded, you risk destroying it. 1st upgrade - 10% chance. 2nd upgrade - 25% chance. 3rd upgrade - 50% chance. 4th upgrade - 75% chance. 5th upgrade - 90% chance. These upgraded weapons/armor could also be traded. For non-smithable equipment, a new ore could be added, or perhaps have a player smith help out an NPC smith. The player would have to bring in some bars, and then help out the NPC with his smithing level. I also like the idea of being able to add things like the Grenwall [bleep]es and making them untradeable is good to. This way smiths can make money by selling upgraded armor, and show off their smithing with armor only they can make :D.
