Dragon forging.

I was thinking of a mod since there are no dragon weapons. It would be neat if you could kill a dragon and only when it is on fire would you be able to use it as a dragon forge. You would have to carry the tools and resources to do all your crafting very soon after the kill.

I was thinking maybe use exsisting metals and once you use the dragons fire they become infused with dragon power thus becoming dragon weapons. Does this sound like a decent plan or am I just dreaming.
