This is highly unlikely for the sheer fact that most people from Chicagoland (Chicago suburbs) would ever willingly relocate to, or conduct all of their business/social life, in Rockford. Regardless of any Outfit or non Outfit reason, Chicagoans would not shift their lives to Rockford.
It would make more sense to join 26th St. or Cicero than to join Rockford. Outside of Illinois, who really knows of Rockford anyway?
That isn't how the Mafia works. If there's action to be had in Rockford (which there certainly is), then gangsters will flock to the light. It doesn't matter whether or not Rockford is a fashionable destination. If there's more action/profit to be had up that way than down in Chinatown/Cicero, then they will certainly head that way.
Do you think Philly/Lucchese guys want to relocate & do business in a boring toiletbowl like Jersey? Of course not, but beggars can't be choosers.
