I own a Weber Kettle 22.5" grill that is used exclusively for smoking meats. I was wandering if the following mod has ever been attempted. Take a smaller grill, like the Weber Smokey Joe, and use it as a firebox for the 22.5" kettle. Use aluminum venting to carry the heat and smoke from the grill used as firebox to the bottom of the Weber 22.5" kettle. Would something like that work? Has any body tried it?
