Over here in Europe it's very common to have criminal organizations that got 10 to 20 core members at most. Everybody else that hangs around those core members are usually fringe wannabes, ass-kissers or dumb cannon fodder that's used to do some menial dirty work. And in this case I'm talking about top tier criminal organizations that are involved in transnational organized crime and make tons and tons of money.

I see the Outfit with their assumed 20+ core members being looked at as a dying enterprise, but the way I see it you can have an extremely viable criminal organization when you have more than 20 core members. You got to realize that in the streets for every hardcore career gangster there can be more than fifty fringe players, wannabes and suck-ups hanging around said career gangster.
