You can always get a visconia or imusa 32quart tamale pot and some extra grates and nuts/bolts and make a smoking chamber for your smokey joe. The mod is called the mini wsm. You can always remove the tamale pot and use the smokey joe as a grill.
The mod can be done for less than $40 and if you do a 2 grate mini you can hold a decent amount of food. I can cook 2 9lb pork butts in my mini without any issue.
