Called the Ceramic Grill Store. They said their Expander for the Kamado Joe Big Joe fits the WSK and raises the cooking grate 5 inches without crowding the lid. The cooking grate would actually rise 4 inches into the lid because the WSK's lip on which it would rest seems to be about one inch below the rim of the cooker similar to what is seen in the pic below of the BJ. So I've got a possible bailout if the WSK can't do what I want out of the box. There's a half-moon grid permanently welded to the rack and another half-moon grid that is removable. It's a little less real estate than a 20 inch grid because the removable half-moon has one wire removed on the side facing out toward the front of the cooker. You may be able to see that in the pic. One thing I like about this is that the rack is one solid structure on a ring that bears along the entire lip where the WSK cooking grid would bear. That's seems more rigid than many expanders that bear on legs. The CGS Expander adds $118 to the cost of the WSK.
My preference is still to operate with the WSK out-of-the-box config if it can handle my peculiarities.
