That's why I love this idea of Tim being the one to realize that Gotham needs a scary urban legend to haunt the criminals, and creates an entire persona to do what none of the others ever did except for Bruce in the early years.
The "down to earth" isn't a niche. There are dozens and dozens of other heroes that also have that, including people in Gotham City. It doesn't make Tim any more special.
