If Marvel and DC ever create more Amalgam Comics (where they combine their characters) I think Matt Murdock, aka Daredevil, should become Batman. He would be as blind as a bat and have a radar sense!
What should the character be called? Bat Devil? Devil Bat? Bat out of Hell? Bat Murdock? Hmmm, actually it might be cooler, if he just stayed regular Batman with his regular costume, but Murdock was in it.
