Having Batman in Gunn's DCU is stupid anyways. Mr Terrific already takes that role
Hopefully clayface is just a standalone like Joker and does not hint at being connected to the DCU. For Batman related stuff just focus on Reeves' Trilogy and add fantastical elements. The stage is set for stuff like that anyways with Gotham being completely flooded and they could have the further degreetation of Gotham turning into some type of No Man's Land scenario. They could even reason the fantastical elements through illusions/hallucinations (fear gas/Hugo Strange's meddling/ Mad Hatter illusions) and Gotham generally just getting crazier because it's a total shitheap after the flooding. You could have condiment king being a guy who uses mustard gas, moth man as another batman copycat, have your black rovvin - but make him Terry McGinnis and not Dick . Mad Hatter puts some hypnosis on Batman which leads to encounters with ManBat, Poison Ivy, Creeper, Clayface, Maxie Zeus - kinda like the Arkham comic. Joker should play a sort of Hannibal Lecter role and not really the main antagonist
