This isn't The Origin's of The Joker it's the origins of a Joker

This is a Joker that we haven't seen before this this is a Multiverse Joker, a Martin Scorsese like universe.
I wonder if this type of movie could work with another Batman Character, or could they make a Martin Scorsese like Batman movie with Bruce Wayne and we watch him become The Batman? in a Scorsese style.
