You certainly can, but I’m not sure it’s beneficial. The moisture retention due to the efficiency of the kk is second to none, to the point I regularly see puddles of moisture on the ground below the draft door. I’m also not sure of the benefit for the same reason I cook fat cap down. As a protein heats, moisture is expelled, not absorbed, so I don’t believe additional moisture in the grill will help.
