The No Man's Land arc would be a nice nod here though it's likely not the case, they would have to incorporate so many complex story elements into the narrative on top of what is already on the table which just isn't feasible.
The central vibe I'm getting from the poster is all is not well in Gotham and the city is on the brink of total implosion not only from the escalation of crime and the vigilante activities of a now fugitive Batman but a third external force closing in to end it. If there is any truth to the speculation pointing to the return of the League of Shadows this flick would properly bookend the trilogy.
