CT, the short answer is no. You can do some things without the water pan in WMS, but they involve higher temp, short cooks. The operating theory behind the BDS/UDS requires a larger separation between the fire and the cooking racks than you can acheive in the WMS. You need 24 inches[to me that is the minimum, more is ideal] in order to cook directly over the coal bed and still do low-and-slow.
