Mig is used on automobile bodywork, so it sould be possible to weld really thin steel, the unknow parameter is the resistance of weld on these thin tubes.
Automotive sheet steel isn't as thin as you might think, especially compared to framebuilding tubes. Most steel framebuilding tubes will have butts that are ~1mm on the thicker end of things, whereas automotive sheet steel starts at about 18g (~1mm) and goes up from there, in some instances going up to 10g (2.59mm).
