OK I remeasured.
The distance from the front of the nut to the middle of the 12th fret is 313mm, thereby a scale length of 626mm.
The above photo shows that with the Wilkinson bridge covering the plugged holes, the end of the PBG adjustment screws do not make it to the scale length of 626mm.
The below photo shows that if I move the Wilkinson bridge forward so that the end of the PBG adjustment screws are roughly in line with the scale length of 626mm, the plugged holes are quite visible. It would also require a small amount of routing.
