There, OP. I've improved it a bit. I think now you may be steps away from having your own show in History Channel.
Seriously now, think about what you want. You are ultimately asking the game to remove all bad traits. If you are going to have the player be able to kill an "imbecile" heir without any sort of limitation and/or punishment, you might as well just remove the "imbecile" trait
