What If The Batman started the DCU?

In this hypothetical scenario, the final film in the DCEU would be James Gunn's The Suicide Squad, the subsequent Peacemaker and Waller running concurrently as an Elseworlds story. After The Suicide Squad, every release date is up for grabs and every project is prone to change to fit the new plan for the DCU.
