The only thing that would make this interesting at all to me would be if they set it in the original time period:
Golden Age
In Batman's first appearance in
Detective Comics #27, he is already operating as a crime fighter.
Batman's origin is first presented in Detective Comics #33 in November 1939, and is later fleshed out in Batman #47. As these comics state, Bruce Wayne is born to Dr. Thomas Wayne and his wife Martha, two very wealthy and charitable
Gotham City socialites. Bruce is brought up in
Wayne Manor and its wealthy splendor and leads a happy and privileged existence until the age of eight, when his parents are killed by a small-time criminal named
Joe Chill on their way home from the movie theater. Bruce Wayne swears an oath to rid the city of the evil that had taken his parents' lives. He engages in intense intellectual and physical training; however, he realizes that these skills alone would not be enough. "Criminals are a superstitious and cowardly lot", Wayne remarks, "so my disguise must be able to strike terror into their hearts. I must be a creature of the night, black, terrible..." As if responding to his desires, a bat suddenly flies through the window, inspiring Bruce to assume the persona of Batman.
In early strips, Batman's career as a vigilante initially earns him the ire of the police. During this period Wayne has a fiancée named Julie Madison. Wayne takes in an orphaned circus acrobat, Dick Grayson, who becomes his sidekick, Robin. Batman also becomes a founding member of the Justice Society of America, although he, like Superman, is an honorary member and thus only participates occasionally. Batman's relationship with the law thaws quickly, and he is made an honorary member of Gotham City's police department. During this time, butler Alfred arrives at Wayne Manor and after deducing the Dynamic Duo's secret identities joins their service.
