Way beyond my pay grade. I bet experienced Luthiers even have problems drilling two post anchors at exactly the right distance, perpendicular to body, and lined up with the neck. Seems like it would take a CNC.
Not for nothing, but all this takes is careful measuring and marking, and a decent drill press with the right bits. I'm not a luthier, but I did shop work like this for years (not on instruments) and even brought my guitars in to work on them after hours from time to time, including filling and redrilling holes for a TOM setup. I'm not saying you should keep the guitar, but if it came down to it, that issue should be easily fixable.
