I am getting the idea that Batwoman will live in another Earth separate from Earth-1 or Earth-38 based on how it seems like the crossover will be on a different Earth.
With people switch identities maybe Wonder Woman could show up?

Favorite Characters:
DC: The Flash (Jay & Wally), Starman- Jack Knight, Stargirl, & Shazam!.
MARVEL: Daredevil, Spider-Man (Peter Parker), & Doctor Strange.
Current Pulls: Not a thing!
This definitely has the potential to be the best crossover event - and I'm saying this as someone who absolutely LOVED 'Invasion' and 'Crisis on Earth X'.
Oliver Queen as the Flash and Barry Allen as the Green Arrow is intriguing. It reminds me of those old imaginary stories and other crazy Silver Age stories which had Superman and Batman switching places.
JWS returning as 90's Flash is DEFINITELY going to be a major highlight for me.
A while back we saw the Kent farm from Smallville being used as a shooting location. Now it could just be a neat reference to a past piece of Superman media, but could it be possible that we might see some other notable characters/actors from past DC adaptations? Tom Welling Superman? Justin Hartley Green Arrow? Lynda Carter Wonder Woman?
