I think in the early 80s NY families did physically act to back an ally, like when Gravano whacked that Scarfo rival on Castellano's behalf. So I don't think Salvie would stand a chance against Scarfo.
Nevertheless the commission felt betrayed by Cappanigro and the Genovese wanted him whacked out long before he hit Bruno. Salvie was well liked and trusted by everyone so I don't know that the NY families would have interfered if they thought Salvie could do a good job. Remember they knew he was good stock because of his father and the mob is all about the $. Part of the reason ( probably the main reason) Capponigro was hit is because Funzi wanted his sports book which reportedly brought in 5-6 million a year. I really think the financial gain was the main reason for Cappanigro getting hit as opposed to "upholding the rules" which the mob bends and breaks routinely when they stand to profit.
