I faded after moving to a new city, but I didn't plan in advance to do it, it just happened.
If you don't want your publisher card sent, move to the next town and never attend a meeting. But since you mentioned your parents will be involved from time to time, I'm guessing that isn't an option.
When I moved, I was a MS and the elders later sent a raving letter of recommendation. Since I was burned out, I deliberately kept my hours low so I wouldn't be immediately appointed by the CO when he came around. I wanted a break. As it turned out I never got my hours back on track and eventually became inactive. It's been years since I've been to a meeting.
If you attend meetings I don't think you can do anything about the letter. Billy's post above has an interesting scenario, but if you get caught doing it, you'll be in trouble for sure.
