Could there be a Joker 3?

If somehow Joker: Folie à deux becomes profitable, do you think there will be a Joker 3 under a different director and perhaps even a different actor playing Joker? Like Willem Dafoe? Maybe they can retcon Joker 2 and let Joker 3 be the true sequel. An idea:

Joker 3(Won't be called that)will start with Fleck surviving the stabbing. He's been there 10 years and still receive abuse from the guards. One day his supporters set off a bomb in the asylum. The inmates escapes and some even joins Joker. Before that, he finds Jackie and abducts him for torture.

Bruce Wayne will be introduced as a 20 years old young man. He will be a proto-Batman in this by being a agile and athletic private investigator to track down the Joker and his men. A straight up crime-action neo noir film. Good idea?
