Unattainable Ideal
First things first:maddman75 said:While I like to think I'm a pretty good DM, and people always show for my games, I know where I could use improvement.
People always show for your games. This is good. This means they're having fun. Take satisfaction in the knowledge you're providing entertainment -- even if it isn't the sort of entertainment you want to be providing. Most people aren't very good at providing ANY, so props to you.
You know where you could use improvement. This also is good. Most people aren't very good at knowing what they aren't very good at.
Best bet? Tell your players about the sort of campaign you want to run. Try it just as a limited-run sort of things -- five sessions with all-new characters and an all-new story and see if they'll give it a whirl. If they'll at least try it, you're probably on your way. If they won't, find folks who will (not easy, I know, but at least you're not wasting your time trying to get these people to do something they don't want to do in the first place).
One thing to keep in mind about "character-oriented" games is that if their characters are getting killed off with significant frequency, the motivation to create detailed characters is hard to generate. I'm not going to invest much energy in a character I'm only going to place twice. If you know what I mean.
