It's a terrible idea. Through holes should be drilled in the exact center of a pad +/-.

Have the two holes go out back and settle this. Whichever hole returns, that hole get to keep the pad. The other hole needs to get its own pad. End of story.

There is nothing wrong with ganging two components. Each gets a private pad which are connected with a nice copper trace.
