I get the feeling that CaptainClown might possibly like an adaption of Gotham Central for the small screen.
The only downside to that would be how it's advertised - as flickchick85 said it comes down to which network it's on. Being from the UK I don't know most of them but HBO always seems to deliver with their programming - at least any that are available over here anyway, which is a lot if you're willing to channel hop for it - and I think they'd be able to make it clear when marketing that it's not a Batman show as such. Just a show featuring him.
Another cool thing about that would be keeping an element of mystery to Batman as he wouldn't be the main focus.
