I have been thinking of an idea for a (quite ambitious) mod for a while where basically, groups of bandits roam Skyrim, and whenever you kill the leader, you can get the remaining bandits to follow you instead. You would be able to inhabit a bandit hideout which you have cleared and launch tactical raids on villages/huts. Eventually you could use your reputation to influence certain people, e.g. recruit other bandit hordes & pay Jarls/noblemen to gain certain benefits (like ignoring if you commit a minor crime).
I know it's a rather large request, and I'm happy to do it if no one else will, but I am a) inexperienced and

Oh and p.s. for God's sake add some challenge, I don't know what Bethesda were thinking letting you kill dragons at level 3.
Thank you in advance
