[Toy Soldier]

I sort of think, if they're going to continue, they'd be better to do a soft-reboot than a recast and continue? Have Ruby's batwoman actually leave and a whole new character take the title (even if it involves something convoluted like writing in another Wayne cousin). Keep the supporting cast that works, and take it from there.

Recasting the same role with a new actor is (in my opinion) not likely to work well. It doesn't even work in soap operas. Actors bring part of their personality to the role and it fundamentally changes the character.

They even had to essentially write this into Doctor Who lore as part of the process... They established early that regeneration changes aspects of personality and not just physical appearance. Because casting a different actor to play the same character "with a new face" never quite hits home.
