Having access to a Bridgeport Mill would also allow the hole to be very accurately located.

Yes, I'd agree with your thinking Rick, but I'd make it of steel (tool steel if possible) the harder the better, less chance of the drill wearing the hole after repeated use.
Some form of saddle clamp around it and tying it to the base of the carb would be solid enough.
Only Mr. Weber will ever know why he released IDAs with only two progression holes.
The are 4 and 5 hole DCOE carbs now.
