As far as Gene Gotti is concerned he still has two brothers who are members of the gambino family. Also his two nephews are associates. Some of the old Gotti crew are still active/semi active too like Tommy Cacciopoli, Jackie D'Amico and Lenny DiMaria, not to mention all the guys that were made by Gotti. He could do like Limone did:

"In that time, prosecutors said, Limone returned to the same neighborhood and met with some of the same people he knew when he was rising through the ranks of La Cosa Nostra. He was regularly seen at a butcher shop and a coffee shop in the North End, receiving visits from convicted members of the Mafia, according to court records."
