In my Western involving the outlaw, Mike Wolfletter, and the Irish kid he finds (they're both on a 'revenge' quest of sorts), I figured I could set a dividing line from where one POV ends and another begins. Basically, it could work like this. 10 or 20 chapters total. The first 5 or 10 deals with Mike where we see the world from his POV, his issues, and his goal. At the end of the 5th or 10th chapter, he dies in a scene involving a train that becomes derailed. The last half of the book, the other 5 to 10 chapters would be from the perspective of the Irish boy, when he takes what he's learnt from Mike and completes the journey and becomes the hero of the town. Would that be a good idea or no? Too cliched? I mean, the whole 'cowboy dies and tagalong companion avenges him and becomes the hero' sounds like it's been done before.
