Sounds likely we'll end up getting something involving Poison Ivy and Batgirl, as well as the other Sirens. Even if they don't make sets for the movie (LEGO only seems to do DCEU Batman or Superman), LEGO will try to cash in on the popularity unofficially, like how we conveniently got comic-based sets including characters from Suicide Squad around the time the film came out. Makes me wonder if we'll get new versions, maybe reusing/recoloring parts from the LEGO Batman Movie.
