It would take away the fun of the animated series.
What I loved about the animated series was that it wasn't just a great Batman series, but it was a great animated series... right down to that Looney Tunes sensibility of having symphony notes played to the beat of Joker tip-toeing up the stairs or Batman leaping between two parallel building faces back and forth. It was like they took all the great elements of WB animation history, and transposed them onto a great action adventure series PLUS Batman coolness.
A lot of that greatness would be lost in trying to copy it into live action, such that you'd be better off trying to build a great live action TV Batman from the ground up with attempting to reference a previous work in another medium.
