It is my belief that you will not get the airflow you need. As the heat rises, the draw from underneath will be strong to replace the air, however most pots I have seen have small drainage holes.
I guess the only way to know for sure would be to try it out and let us know. If it is wind you are concerned about, from what I've read on here, the only single way to combat wind is with a wind break. You have to prevent the wind from disturbing the air in the cooker. The only smoker on the market that i know of that does this by itself is the WSM.
