Keep in mind Batman is young at this point so his rogued and allies should reflect that so he won't have a extended Batfamily at this point and Dick Grayson wouldn't be Nightwing yet ect
Also try and use actors actually rumored for roles in the trilogy Andy Serkis,Nicholas Hoult,John David Washington, Jamie Foxx, Vanessa Kirby, Giancarlo Esposito ect
