How would you fix the Robins and Batgirls' origins in a new modern timeline?

[Flash Gordon]

Richard Grayson has none of the circus background. Instead he's a bit closer in age to Bruce and acts as a Watson to Bruce's Holmes. He's a young working class guy who deduced the Batman's identity early on and got himself involved in the fight. He's the lighthearted side of the dynamic duo, as Robin. He could have a background in martial arts, and Bruce perfects him. He's more of a brother than a son. Bruce's best friend and most trusted ally. He still goes by ROBIN and is a full fledged member of the Justice League.

Tim Drake never even met Batman. He just dresses like Robin and pretends to be the now legendary crime fighter. He's a smart kid who makes makeshift equipment in his parents garage. He goes after some gang violence. I'd try and keep him separate for quite some time. Young Justice is formed by him, and everyone there thinks he's the real Robin. Eventually this makes him a target for villains and he gets in over his head, his suburban life falling apart, and needs the help of the real Batman and Robin. He wouldn't know the secret identities of his mentors but he'd have a way to reach them and unofficially work with them from time to time.

Damian remains as is, but aged in real time. He mimics Richard for a while, trying to also be Robin. Sometimes he calls himself Batman, also.
