Reverse Batfamily/Gotham vigilantes have weird side effects because if you include Bruce, then Duke, aka Signal, becomes the first vigilante in Gotham.

Idk if this is exactly the correct order, and I might be forgetting someone.

1) Duke (Signal) - meta caught up in a big disaster that pushes him into becoming the known daytime hero of Gotham

2) Damien (Robin) - raised by an assassin cult

3) Cassandra (Batgirl/ Blackbat) - raised as the perfect assassin

4) Stephanie (Spoiler/Robin) - child of a b list villain

5) Tim (Robin/ Red Robin) - neglected child and hero stalker

6) Jason (Robin/ Red Hood) - orphan and street kid

7) Barbara (Batgirl/ Oracle) - daughter of the police commissioner

8) Dick (Robin/ Nightwing) - circus kid and orphan

9) Bruce (Batman) - orphan and nepobaby

Even keeping the basics of their stories is going to be problematic.

Damien can't be Bruce's kid?

Idk where Huntress goes or if she counts.
