What If the Arrowverse was in the DCEU?

The premise is pretty simple, that being a hypothetical universe in which DC was telling their stories through one definitive universe. This includes movies, and that part is right here. Because of the added challenge of being complementary to the movie universe, this universe will have to accommodate for the choices I made there.
