I have q3200 and found you can take two weber charcoal baskets and place them on the q3200 upside down on the grill grate about 9-10 inches apart, or just enough to let the pizza stone rest on the top end of each basket, then heat up the grill and place the pizza on the stone. Placing the stone up on the baskets keeps the bottom of the pizza from burning and it also gets the pizza close to the lid so the top of the pizza cooks also. This will work, you just have to get the temperature up.
