Would it be possible to simulate some of the effects of a WFO by insulating the lid of a propane grill and leaving the heat on during coking? I have about 1 1/2" gap between two layers of stainless sheet metal that make up the lid to my grill. I could insert either kaowool or insulafrax blanket in this gap which may help to distribute the heat evenly from the top and bottom. I would leave a pizza stone on the grate and get it to probably 700+ degrees prior to cooking. What do you think?
