The Scaled Furnace should work like Fire Packim Baggims

Some might say that the scaled furnace is perfect as it is, and Warly's/Willow's/Walter's cooking speed would be left behind if it worked like that, but think about it, it's a Furnace, and it's a D.fly drop, it's not meant to be built day 1 or something(even tho some people can), so their cooking speed would still be very useful in the early game to mid game and such with the Firepits and campfires.
The heat it provides is really nice, but it's only an eternal firepit, with not that much light,  and would be nice to not have to make a torch to burn things to ashes or keep clicking on the furnace to cook stacks of foods, Idk if it would need an opening animation , make just some effect to say that whatever is in the furnace is ready. 
I see it working with 1 to 2 slots, would be enough,  the cooking time would be slightly faster than Warly's fast cooking a pack of food. Could also be instant cooking much like Fire Packims.
That's an Idea, what do you guys think?
