How hot will your smoker get, jonreo? I've never tried it, but I found a few recipes for oven-roasted corn-on-the-cob. They all called for 350 degrees and the corn is cooked in the husk.
If you are using a Cookshack, it is basically a smoking oven. If you can't get 350, go as high as you can go. Put the corn in far away from the heat source (top or second shelf).
I would try soaking the whole corn with the leaves on in a pot of cold water for 30 minutes first, then shake off the excess and pop them in the smoker. The water inside those husks will help steam the corn. That might help compensate for a slightly lower temp.
I don't know if you'll get any smoke through the corn husks, but if not, it should still come out as good as corn roasted in your oven.
If your corn is already husked, then foil would be the way to go.
If you try it, let us know.
