Yup, it would be pretty easy to do because he’s essentially just a street level vigilante. I always envisioned something like this
Make him a little crazy where he can speak/communicate with the city. Maybe because he’s been sniffing on scarecrow’s hallucinogenic gas for too long. While still keeping him grounded in reality through real life crime, conspiracies, etc. it would give the series an other worldly sense by being able to showcase cool psychedelic scenes and still keeping it grounded in reality.
