Why do you need an "oops" rivet? Is it somewhere that shows? Usually the AN470 rivets are in places that won't be visible, so you could just use an AD5. If it does show, and if the hole isn't too much bigger than #30, you might try pre-squeezing the rivet. You'll need a slightly longer rivet of the same diameter. Put it in a hand squeezer and as you squeeze, it will get a little fatter, and a little shorter. Do it carefully though, as the longer rivets tend to bend.
Good luck.
