Ok, this is just an idea I had. I'm not that experienced with modding at this point, but this sounds like a fairly big thing to request. My idea is a post-game (or at least, very late-game) quest line. Your character starts hearing reports of the presence of a very strange group of people-they appear similar to the BoS, but their armor's painted Vault-Tech blue. They're running around attacking settlements or otherwise doing things your faction does not like. You investigate this group of people, and you eventually find out who they are. You see, once Elder Maxson took over the BoS, the Lone Wanderer became disillusioned with them, and left. He was let back into Vault 101, and even became their leader. He since reorganized them into essentially his own version of Lyon's BoS, and since relocated them into the commonwealth, and declared war against your faction. You eventually locate their secret base, and then you have to get inside of it. Fight or sneak your way through it, and then get to the Lone Wanderer's chambers. You talk to him for a moment, and he explains his motivations for declaring war against your faction: -The Minutemen are too incompetent to fight Mirelurks and are rather sycophantic towards a guy who became their leader for practically no reason at all. -The Railroad only wants to help Synths, not humans. -The BoS turned against the ideals of Lyon. -The Institute reminds him of the Enclave and uses Synths to control the Commonwealth. At which point, you can A) Fight him, or B) Pass a few speech checks and convince him that your faction is what's best for the Commonwealth, at which point he stands down. Your speech checks boil down to: -The Minutemen are apparently competent enough to fight off the Institute, and it's not like the Lone Wanderer's leadership is much more legitimate the the Sole Survivor's. -Helping Synths is the first step to solving other problems in the Commonwealth. -Synth technology is a threat unlike anything that Lyon ever had to deal with-returning to the old BoS MO is simply necessary to stop a robot rebellion. -Tell him that the Institute is the kind of organization his Father would have worked for, and compare its operations to Project Purity.
