Just to bolster your confidence... I did the drill out and plug with dowel version of the fix, admittedly on a very cheap neck, and made a horrid job of it. For someone who likes woodworking I was ashamed of myself. However, it's been fitted to my office beater-bass for several years and has been completely solid. No problems with movement or strange sounds coming through the pickups or when played unplugged. Have a practice run on a bit of scrap and go for it!
