Red Hood and the Outlaws, the resurrected Robin that chose his identity based on Batman's failings and choses means that are more ruthless then Batman, Damian, the really young Robin who has a hostile disposition and treats everyone with contempt due to his upbringing and even Cassandra Cain, the mute/near mute that has only known fighting and has lacked a proper upbringing are all character concepts that cast Batman in the role of neglectful fatherfigure so these characters can preserve their edge/base character concept while still being in a heroic role.
Tim, who has parents of his own and isn't really ever meant as such a dark, tortured character, should be easy to make work without demonising Bruce.
