Tracy,
I thought at one time about doing this using 50 caliber ammo cans on a camp stove. I even went so far as making baskets for the parts. Like a lot of us, I got wrapped up in something else and didn't get back to it. Maybe you could pick up the ball, I would be interested in how it works out. At the time I had very little space and thought it would be convenient to blue outside under the patio cover then put the tops back on the cooled can(S)and store them out of the way. Good luck.
Mike
