Looking at the layout, bodging this is going to be fuuuun.

g10, g8, and g4 have pair D routed on layer 6 of 8. Getting to them (assuming I come from the back of the PCB to avoid desoldering the connector) will mean drilling down 250 μm - annoying but not too bad.

g13, g6, g2, and g0, all have pair D router on layer 3 of 8. Getting to *this* from the back side will mean drilling down almost 1.3 mm. That will be decidedly less fun.
