Thats not such a bad idea, tbh...
I'd like to see religious differnences in settlements too. So like Town Cupcake believes that Atom will save them if they devour enough Mole Rat blood, but Town Donut believes that the path of Atom requires rigorous training that can only be learned by surviving a rocket launcher shot.
Good start, good start... though surviving a Rocket Launcher blast? A little too simplistic... Why not instead go through a cavern full of Radiation, Geckos and maybe a single Death Claw at the end? These religious folk consider this area to be hell on earth.
