Jack Slash and the Joker

Jack Slash is an attempt to port the Joker to the Wormverse. The Joker represents a villain archetype that is very popular, but I really feel like Jack is a poor imitation, mostly because Worm tries for a certain amount of realism and the Joker is larger than life. Jack has goals and agendas, and I get the feeling he really likes being Jack Slash, that he is in love with the persona. Compare to the Joker. The Joker doesn't care about being the Joker, he just is the Joker. He is a primeval force of chaos and charisma that has glimpsed the truth behind reality: everything is a joke. Whether you find the joke funny or not is up to you, but he isn't some angst ridden nihilist. Jack cheats, he isn't actually more than averagely charismatic. If he turns a hero to evil, its because he has a super power that lets him Thinker/Master capes, not because he's genuinely persuasive or creative.

So, does anyone know any fics where the Joker and Jack Slash meet or where similar comparisons are made? Maybe Jack falls into the DC universe or the Joker is transported to Worm or similar?

Somewhat relevant fic: Prodigal Daughter - Taylor is Jack's daughter but adopts a much more Joker-like persona
