Refitted Clubs

[dant]

I am thinking about getting my son used golf clubs. I am also going to get him fitted. I was wondering if they can refit someone with used clubs. He has grown from his last set (2"). I know that club length should not be a problem. But lie angle is what I am wondering about. I think depending on what the club head is made of you can give it a new angle if needed.
Thanks
