Lots of interviews I’ve seen with the creators and production say they’re open to crossovers, but it won’t happen this season due to the desire to have Naomi’s first season be more about her than crossing over with other shows. That’s fair. You want to establish your hero’s story before having them meet other heroes. But they’re at least open to the idea, which doesn’t rule it out entirely. I think it’s gonna depend on if the show is a hit, scheduling and if they have the right story.
They’re open to it, but will it happen? I think so, but it may be a while. Stargirl is about to hit its third season and it hasn’t crossed over with any of the Earth Prime shows, but we know it’s only a matter of time.
My biggest question for Naomi as a whole is if they can get the story rolling. The pilot has a lot of fantastic ideas, but the pacing was a problem. This could just be the pilot. Eager to see what this show has to offer.
Also, here’s some of the interviews I’ve seen where they say they’re open to it. I like to cite my sources:
