DIY Idle-eze?

Anyone ever consider making an Idle-eze air bleed down the center of the carb body ala Speed Demon? Drill a hole, tap it for a screw in air bleed like from a bike fork? Instead of the common idle adjuster that throws the transfer slot out of whack or the destructive throttle blade holes. You could still run the air cleaner stud but would have to drill a few holes in the stud tower to feed the bleed. This would just be a controlled vacuum leak, right? No fuel.
