Have you ever wanted to join The Lost Motorcycle Club in GTA Online? What about working together with infamous street gangs, such as the Families or Ballas? It would be incredible if there was a way of creating your own mafia syndicate within the game.
Unfortunately, at this stage in the game all you can do is be a lone street gangster and nothing more. Rockstar needs to create new characters that would act as intermediaries between you and the factions. You could join one of the factions and accomplish a number of unique quests that would increase their trust in you. On the other hand, it would also increase the hostility of other gangs towards you, just like it was in GTA 2.
