I can appreciate what you're trying to do, but this is one WoW idea that should stay over there. (Idea seems based on Reforging)
There are benefits and drawbacks to crafting recipes and mats. All mats are good, and all mats are bad. Use the right set of mats for the right item. The beauty of crafting in this game is that you can pick the mats and achieve the quality that you want; it's more than the push-button-get-bacon crafting from other games. There are already ways to boost items beyond what the mats would appear to allow, using specialty crafting plans and specialty tools.
The really good items should be rare, and hard to craft or obtain. And the chance of failure should always be present. If you add new super-items, the entire game would need to be rebalanced. If you can't do something alone, don't increase the capabilities of the items, just get some friends.
