My personal preference would be to change the allowed tolerance on the drill
size. By increasing the plus tolerance then the larger hole would come
inside the plus tolerance of the smaller hole. If you are dealing with
Olimex then this is the way they deal with slightly differing sizes on their
cheap deal, from the way I read their web page.
