Not even close. (81 megapixels is 9000 by 9000, and the moon only takes up about the middle 1/9th of the image, so it's about 3000 pixels across. So that's over a km per pixel at the very front of the moon, and even worse at the edges where the surface is at an oblique angle to our view)
Also, I can't remember the source (maybe it was a "What If?"), but I seem to recall that it's actually to create a lens that allows us to focus a point on the moon to allow us to make out current man-made items on the surface of the moon.
