Yes, thanks, I thought about this option too.
My main concern is my current understanding that superchargers are not street legal in California, so I am currently assuming that I will have a problem with inspection in Massachusetts as well. I think the regulations are the same.
So for me - changing the X-pipe and the tune to get an inspection is just a lot less work than with a supercharger.
