You expect 1000ers to endorse most decent comments they come across that aren’t greyed out yet. Based on how many votes most comments currently have, I doubt that would be the case. Unvalidated comments would appear greyed-out, therefore suspicious, and most 1000ers would assume there is something wrong about them that they haven’t figure out. Especially if they expect to be punished for validated anything that isn’t exceptional… I’m not sure what ratio of comments you expect to weed out, but I expect most will be gone.
