Does everyone remember the famous film, Kurosawa's "Seven Samurai"?

I was playing Dragonfall again the other night and reflected that even if you try to play a "good guy" character you still basically end up killing people for money, unless you decline a lot of jobs.
Today I remembered the "Seven Samurai" where a bunch of disenfranchised and impoverished samurai defend a village against overwhelming odds in exchange for three meals a day.
Maybe it could be a great set-up for a Shadowrun campaign. You could easily have a village somewhere menaced by a large gang and defended by a handful of down-on-their luck sammies.
I could sort of see a samurai character growing tired of the body-count rat race of taking runs in the normal manner, and who might see something like this as a situation to socially establish him/herself in a small village and sort of get away from it all. Or maybe a character sees it as atonement for past misdeeds. Maybe there's some Rambo IV syndrome going on.
The more I think about it, with the right player characters, it sounds like it could be a really compelling and very tactical campaign.
