I think I've decided I will block 10 of the holes and re-drill them 27mm apart instead 24, 24.5 or 25mm apart as they are currently. This will also allow me to line them up better. But this means I will need to work out how I am going to hide the plugs. Veneer would probably look best. Or going for a solid finish on the headstock. I will need to investigate the options.
