There's a mod that does most of that called Fallout Wanderer's Edition, I tried it but it wasn't my thing, I didn't like the feeling of having restrictions put on my freedom and I know that I don't have the willpower to put these imaginary restrictions on myself without breaking my own rules.
Hmm yeah, I've heard of Wanderer's Edition. I never bothered to install in though as I usually just like to put "house rule" limits on myself.
If you have a PC you could always use console commands to align yourself with a faction (Enclave, raiders, Talon company e.t.c) and roleplay as a member of them.
And if your on the Xbox you could use the mesmerizer to get all the raiders in everygreen mills on your side, then rolepay as a raider.
