For a brief period I considered the possible use of a center weighted filter. But once you see how "hard" this hot spot is; and without contrast; it becomes fairly evident that any available center filter would not work. You'd have to go through mind numbing tests; looking at all sorts of various "donut" configurations in the image to come anywhere close to a "block" correction. And even if you could get there and correct for the "over exposure" you'd still have to deal with the lack of contrast in that "spot."
