In fact, considering the retconned the Arkham scene and possibly Starfire's death, as well as having Martian Manhunter as DLC in the previous game when he died in the comic, there's more of a chance of the game ignoring the comic.
She may have a chance at being DLC, but that chance is not very high, especially since we haven't seen her do anything that would merit a space (unless the all-access video hints at her being DLC) when there are other, established characters they can choose.
