Yes, Vito has elements of other US Dons in addition to Costello. He was the biggest importer of olive oil (like Joe Profaci). He groomed his son to be his heir, and the son was betrayed by one caporegime while another stayed loyal (like Joe Bonanno). He was the victor in a war in the Thirties and left his foe dead in a restaurant (like Salvatore Maranzano). You might also say he was first among equals (like Charlie Luciano and Carlo Gambino).
