in a scenario in which Marvel beat Detective comics to the character of Batman, don't u think Matt Murdock would fit the role better?
think about it:-
1- he is blind (one of the characteristics of the bat) and a critical point in the conversation.
2- he depends on sonic waves (radar like) to feel his surroundings (hint at a bat? maybe)
2- he also lost his beloved ones, like Bruce lost his parents.
3- he also works in the night and in one of the darkest crime neighborhoods - hell's kitchen.
4- he is a lawyer, which makes the fact that he fights crime as a knight of justice, have more sense to it.
4- his character is as dark as Bruce, if not more.
5- he is far more agile than Batman, which gives him a point to me, and brings him closer to the simulation of a flight of a bat.
in my opinion Daredevil woul've been the perfect Batman, just give his suit to Matt Murdock, and we're set.
