Came out with an idea? Congratulations, I hope your family is accepting of your lifestyle.
...Oh, now I get it.

I mean having an organization where you could organize companions or something could sort of be neat, but if they're using a system similar to Fallout: NV where your companions just wait in your house/hideout then this would be kinda pointless.
In terms of unique questlines, sounds like something for mods.
