They should cast Kevin porter as the DCEU Batman wearing the Jason Fabok three jokers Batman costume(https://www.google.com/amp/s/amp.red..._1000_variant/)
This costume is perfect because Jason Fabok himself stated that it was inspired by Keaton’s Batman costume and batfleck’s costume
Kevin porter also looks like Batman
the rumored universe merge could mix batfleck and Keaton Batman into one character...who looks like a composite of both
