PC users have already had the privilege to use a mod that allows you to do that exactly. Val's Melting mod I believe. Been using it now, and I must say it really brings a whole new perspective in "not lumbering around with useless armors"
It causes my Skyrim to lock up at the loading screen...I know it's Val's, because that's the only one I have to disable to play.
Speaking of smelting...I haven't seen any device called a "smelter" yet, and the forge won't turn Iron Ore into Iron Ingots...
