One disfellowshiped JW did the "start over as bible study" in the 70s. (moved, reversed first and middle name, got baptized and married). While on a tour of Bethel, met a Bethelite from an old congregation, and was "outed". Got double disfellowshipped, and lost the new family for "lying". poor smuck. lol.
It's easier to simply enjoy life for at least a year, then VISIBLY attend meetings, write some great dated letters spelling out how you have changed, and "fixed" any issues/mistakes every month, ASKING for a meeting. My question IS who would want to go back? yikes. IMO.
