the needles would bepretty hard to do I think. If you have looked at them the angle on the needles is very slight. If you had a micro sized lathe and didn't mind pulling your carbs apart 500 times to regrind the needles to the proper size then go for it! Then the problem of getting bowls set up right... Anywhere over 8-10 PSI would be hard to tune I think. Whenever you wanted to go up on boost you would have to change the needles.
Good idea I think and good luck!
