The flare safe zone is above the line drawn from your ring finger to your PAP.
I'm not a driller, so take this advice with a big grain of salt. You could probably put the pin about 3" from your PAP, just above that line and the CG moved back toward grip center as far as possible to reduce the weighthole size.
Something like:
..........O..........O..................
............................P.............
........................CG.............
...............................PAP......
...........................................
...........................................
...........................................
................O..............V.........
................................A.........
................................L.........
Weighthole would probably end up near the pin?
