Nice one! Now that I think about it, and see that top view, we all have spare, past their prime charcoal grates laying around. Why not cut one down to fit the crescent shape and wire it in? Agree the gap is not ideal, but only when it's time to lift out the spent (and unspent) coals after a cook. It's true for the 22.5 version too, but the gap is smaller. I may give that a try myself - I have a 26er version in the works.
