I would hold off on trying to use a hone. I understand where you are coming from, but I still think it's worth it to be patient and try to find a better solution. It will be difficult to hone with the trans in the car and much more difficult to avoid contaminating the system with fine pieces of aluminum. I'd be willing to bet good money that this is not unique -keep seartching, and good luck!
