The colombos was ever the weakest and most instable of the 5 families. Im agree that persico ruined the family and after the orena war nobody would try to take the boss role.
The colombos are still active and made money, more than philly or the decavalcante but on 100 made men on the streets, half are too old to make money (Sonny Franzese is an ecception) and the others was related to the persico so when carmine will die, alle boy will be the new boss, with his parents as street boss.
If someone would had the power to take the boss role, won't a new war like the 1991.
