Anyone stack 2 WSMs?

I was wondering, now that I have 2 WSMs how it would be to cook on them by stacking one barrel over the other. Has anyone else done this? I would have to remove the top grate screws from the bottom barrel to allow the stacked cook area to slip down into the other. I was wondering about whether the legs would hold that much weight given the idea of cooking on 4 levels(Briskets, Butts, Ribs) all at the same time with the same fire.

What say you all?

It's been done. Go here, and scroll down. I don't think the bottom of the center section will slip inside the top of another, though.

I have an out of round 22" center section that Weber replaced and I tried stacking them and just did not feel comfortable using it.

I do have a Cajun Bandit Stacker and it works great.
