Not sure how I'd feel about that being true. To me, it'd just come off as a cop-out on an interesting take that is Clownhunter. It would be another case of "Here's this surprisingly cool new character, but no wait it's actually The Joker you guys!1! lloooooolllll". And coming right after/right next to the whole August Heart/Godspeed and Thawne thing, I'm not here for that for another cool, intriguing new character.
