Seems overly complicated, but it might work if you can figure out a way to measure the temperature. That said, you're better off going to the store and buying an "oil burner" glass bulb style pipe for $5. If it is at all possible, look I to the GVG. My understanding is that it operates in the same way as the "machine" but I don't have experience with the latter, so not sure.
So yes; it might work.
No you shouldn't use it.
