enchantable furnace/blast furnace/smoker

while the addition of the blast furnace was great now that ores are fortuneable it would be nice if you could enchant furnaces and their upgrades with efficiency since after loading an old world that i was mining out i ended up turning 4 double chests of iron ore into 6 1/2 chests of raw iron and 2 double chests of gold ore into 3 double chests of raw gold and even with a full smelting factory going it took about 2 hours to smelt it all so letting furnaces and blast furnaces  accept the efficiency enchant would greatly help
