A water heater tank is a pressure tank, designed for around 150psig working pressure, and something like 300psig design pressure. I would think a pair of matched water heater tanks with a pair of strap steel "blades" welded to the outside in a spiral would work just fine. Build it, Mike, build it!! If you get one built and post some pictures of it cruising around in the deep snow I bet we'll have several more following. Build it!!
