This kind of reminds me Pirate Batman elseworld of Greg Rucka. Joker was the marquise and Batman was pirate... This was the Pirate Batman's underground movement against The evil Authority Joker. Batman was still the hero but seeing the roles change as the lawful authority joker to unlawful pirate Batman was fun. Batman was going by the name Leatherwing in that story, and i even made my nick name leatherwing for a while because of this story but later on i learned that Nazi Batman also goes by the name Leatherwing... lol I was like OMG people will totaly get the wrong idea... and quit useing the nick name... lol
