I did actually go through with this. Followed Rob's advice and it worked out great.
Drill and tap the holes (6-32 NC tap, 7/64 Drill bit), use a Dremel/exacto knife to round the edge on the top corner of the grip, and Dremel the plastic protruding edge on the underside of the grips so they sit flush.
Feels way better than Hybrid wrap around grips and not as chunky as one might think.
