Agree with Travis, bad idea. It will boil the bejesus out of your beans! Better to drop a cast iron oven onto the lower grate for a few hours at the beginning of the cook. Don't let it sit the whole time. Lot's of good bean info if you search "drip beans".
@OoPEZoO has the recipe I use, it's awesome. Leftover pulled pork mixed in the day or two after is even better.
