It is but it would cost an arm and a leg, but then you would still have your plain controller you got from here. It would be a regular controller though with holes in it.Fredrow does great work and should be able to do this for you. Check him out at http://www.east-seattle-electronics.com/
I was thinking of getting the same thing done but now that development has stopped on the macro controllers I'm not sure if it's worth it.
