The only one I can think of quickly would be Albert Gallo but I'm not sure that he was really made or not when he switched from the Profaci Family to the Genovese Family. And that was a very special case.
I think Trafficante might have had a few guys who switched from Chicago or Cleveland to him.
Usually I think that once you're a formal member, that's it-no refunds or returns.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming
Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
