Luciano not so much, look what he did after he was deported. He helps set up the heroin pipeline. But Costello on the other hand, any other boss would've had a full out war after an attempt on their life. If Anastasia would've survived, the blood bath that would've followed would probably be similar to the godfather. I believe Costello wanted to go legit more than any of them, but just couldn't shrug off his past. Look at Moe Dalitz, he did it right. In my mind he did what many sought out to do. The Italians didn't stand a chance. After Appalachian, no italian gangster was going legit if they had a past. I often wonder what would've become of Siegel of he wasn't killed. I don't think he had the brains like Dalitz.
