Still wont Happen, when Elder Lyons dies, his daughter will take his place, and she is very much a daddy's girl, I don't see her trying it either, or her successor.
And while he says he is helping people, and went native, you also need to pay attention to other factors as well, like the open recruitment, and the giving away of the project purity water for free, everything Lyons does, while helping the people, also gives him, and the BoS as a whole, major points with the citizens of the CW, which causes them to want to join the BoS, and thus, save his dieing order by giving them recruit and numbers that they were losing rapidly due to their previously isolationist policies, a point that is brought up in New Vegas by Veronica.
Hell, Lyons is the male version of is Veronica from New Vegas, she wants the BoS to use their tech to help people also, but the main reason behind that is that in the BoS helping people, people help the BoS not die. He's not just some ultra white-knight who does what he does just because it helps people, he does it because in helping people, he gets them to help him.
It's a mutually beneficial relationship.
