Dean, I suppose I could write a script. The basic principle would probably still follow a G83 peck cycle, although you could add in more pauses and stuff for chip clearing, I suppose.
What kind of drills have you tried using? You might try a spade drill, which gives lots of body clearance, and not nearly so much rubbing land as a twist drill. If it has through the shank coolant, you might be able to take advantage of these passages for getting an air blast right down to the bottom of the hole. This would allow you to drill farther between retractions. I have never tried drilling plastic with a spade drill to see what would happen.
You might also try relieving the edges of a spade drill blade, so that it will cut, instead of rubbing inside the hole. A spade drill may not hog in so badly as a twist drill, if you purchase one without any face rake.
Lots of stuff to try, perhaps someone else has already performed some of these experiments.
