There is no vice versa. Batman has never beaten Wonder Woman one on one.

He developed a plan to do so for Tower of Babel, which relied on nanotech attaching to her brain and putting her mind in the illusion that she was in a constant, never ending battle, which would eventually have overloaded her heart.

Yep. That's the length of ludicrousity Bats would have to go to to beat her. She doesn't have exploitable weaknesses (or at least not any more - the "powerless when bound by man" hasn't been used since the Golden Age).
