I was just looking through Facebook and saw someone post a photo of this. I don't think it is perfect execution. The table looks to be a little too wide to work on the grill in my opinion, but it is a cool concept for a custom build. If you found one of those spools for free or cheap I think you would have to give it a shot. Maybe an 18" with the ash bowl? There would need to be some openings down below I would think just for air too.
