What I want the new #DCTV show to be

If this new show is going to be on the CW (which I find unlikely based on the networks president, but you never know) then I would want it to take place on Kara's earth. This would leave two shows on Earth-1 and two on Earth-38. Additionally, I would want it to be a female lead show.

Ideas:
Batgirl and/or Batwoman
Wondergirl
Zatana

Ideally I would want it to be a Batgirl and/or Batwoman (Basically a female in Batman's family of superheros). This would make sense because batman has been teased to exist on Karas earth and even maybe on Earth-2. The series can take place in Bludhaven or some other city and Robin/Nightwing can be a supporting character much like Martian Manhunter is on Supergirl. But depending on how much Fox and Gotham have the rights to this idea might be the most far fetched.

For Wondergirl would be a cool show to do but for this one they would have to establish that Wonderwoma exists on Supergirls earth (Or on Earth-1 if they want to put it with Flash and Arrow). and the show could follow Wondergirl trying to make a name for herself. This could also introduce the idea of ancient civilizations existing, namely the Amazons and the Atlantians. (Atlantis was teased last season on flash when Jay/Zoom said that Atlantis exists on Earth-2 and he had a friend there)

Zatana would also have to establish Zatara but this might be slightly easier given that ancient magic has been introduced in the universe on Earth-1 via Damien Dark and Constantine. Zatana could be the vehicle to establish magic on Earth-38 (Supergirl's earth)

If not part of the CW and CW-verse then I would still want it to be a female lead. As of right now the only female lead #DCTV show is Supergirl. While we have Arrow, The Flash, Gotham, and even the two shows in development Blacklightning and Krypton.

These are just my Ideas they probably wont happen but I can dream.
