I hoped this would be about converting a meteorite crater into a mirror

  It might still be, creating a disk of 100m in diameter on the moon would need all the help you can get. There aren't exactly alot of bulldozers on the moon.

    You could a bit like in Arecibo, and pick a properly-sized crater ?
