All in all the bounty system is a good idea. To make someone wanted and running from do-gooders. However the current problem I hear all too often.
"Hey, lets but a bounty on him!"
"He will just have one of his friends pop him when it gets high enough to be worth it."
What about a bounty system that allows individual A sets bounty on player B AND sets parameters for who can kill.(corps, individuals, alliances, etc.) or some way to overcome the current largest drawback to the bounty system. If your looking for space on the server to use look into courier missions/player created missions.
