I tend to agree F4 would be a good fit for a series, but to my way of thinking the stumbling block isn't the stretchy guy, but the guy that's a walking rock. Not that it's not feasible on a TV budget (it is) but it's going to be an utter nightmare for what ever poor sod they cast in the role to be under all that make-up and a full body suit the whole. Again, not impossible, but they'd have to get very creative there, somehow. I might also suggest Batman Beyond as having some live action show potential. I mean it's already a proven concept as an episodic format and the future setting would make it stand out from the crowd a little. 'Gotham Central' could have been a good idea had 'Gotham' never existed. Now it would just look like a repeat of a similar concept. I guess they could frame it as a sequel series and seriously age up Gordon and Bullock? But on the other hand: meh. Oh, Catwoman could probably work too. A proper anti-hero show with a Robin Hood type of premise: sticking it to the one-percenters.
