I must respectfully disagree. As noted above, I've drilled out side dots and replaced them with the Luminlay dots numerous times. I wouldn't attempt it without a dill press, but if you have access to one, and rig up a jig to hold the neck steady, it's not all that difficult. Of course this is easier on bolt-on instruments as you can remove the neck prior to drilling. Things do get a bit more difficult on set neck and neck-through instruments like our Alembics.
