hmmm plop a couple of cutouts on the thing to close off the exhaust and turn it into a smoker....
many many variations on a theme here, perhaps hinging the valve covers and hollowing out the heads so you could put grating in there, viola upper shelves for slower cooking! and lighter to boot! Add a gas burner in the intake and mod the air filter a touch and you've got a single burner stove as well!
