Campfire Smelting

I'm working on something for very early game (pre-mining) that would utilize the vanilla campfire for smelting a couple of items (specifically, drying a plant fiber item, which can then be used to craft twine). Looking around, I see that there have been suggestions to include campfire smelting as possible recipes alongside the crafting table and default furnace (and other options), so I know this isn't implemented yet, but my question is: is there another way to do this in the meanwhile, like via a procedure or straight coding?

I'm brand new to this so any explanations might have to be dumbed down just slightly. Thanks for any suggestions!
