I have a feeling that adding in Superman is probably what the redevelopment entails.
I still like the idea of a show were Lois & Lex are the main characters and we see the story unfold through their eyes but you need Superman (or you will eventually).
I hope this happens.
		
		
	 
Man, I wish I'd known about the "redevelopment" thing before me and my buddy started recording our podcast this week; I knew about and mentioned Metropolis, but didn't know they were (possibly) repackaging it along the lines me and my buddy were theorizing it *should be.* I honestly think that Superman's mythos is strong enough to hold a show or two without necessarily requiring him present; Krypton is succeeding right now, and technically, if they were to ever develop a Legion of Superheroes show, it would be one big spinoff of Superman.
But when you bring in Lois Lane and Lex Luthor, you do kind of *need* access to Superman. She's the love of his life and partner in reporting, while he's the archnemesis defined by his feud with the Man of Steel. Ideally, even if you remove personal relationships with Clark Kent, Superman should be the great mystery Lois is trying to solve and the greatest challenge of Lex's life. Any villain you out before them just isn't going to be even a ghost for a challenge before that.
I think the ideal way to do it, and still keep Superman in the background for most of the show, would be to have Lois and Lex both arrive in Metropolis and begin seemingly Superman-less adventures; perhaps Lois starts investigating Intergang while Lex starts competing with Intergang's leader Morgan Edge... And have the first episode end with a subplot where Clark does his first, quiet and street level good deed, like saving a tenement building from Intergang arson, but we don't see it, we just hear about it and see the after effects. 
Like, have the first season feature a subplot of a Grant Morrison-style t-shirt and blue jeans Superman starting to make waves that slowly pick up steam and give the audience larger and larger glimpses of him, becoming a side investigation Lois is running and maybe having Lex seek to manipulate his attacks on Intergang to give LexCorp a leg up on Edge and Galaxy Communications. And if you want to get really creative, have Clark Kent show up in the background of some Daily Planet scenes long before he and Lois are introduced, and maybe try and see how well you can make his disguise (like, maybe Clark has dark normal eyes while Superman has alien glowing eyes, or have the actor shoot all his Clark scenes then work out for weeks afterwards before shooting the Superman scenes to make the physical appearance very different.) The have the finale feature a victorious Lex try to clean up Lois as a loose end, shoot her helicopter, and have Superman make his first real appearance saving her before confronting Lex.
My buddy and I had a bunch of little wish-list things in our Superman on Tv podcast (
https://itunes.apple.com/us/podcast/franchisewars/id1286433288?mt=2#episodeGuid=Buzzsprout-770409) that we think would work in a new Superman show, and I think most of them would apply to Metropolis. Like, two things you can hear about if you give it a listen (and please do!) would be how you could make Clark, Lois and Jimmy have a kind of work-comedy chemistry and maybe even a bit of pseudo-sitcom humor of you had them all live in the same apartment, and one other thing that I think Metropolis really needs: a new reconstruction of Jimmy Olsen, complete with whacky adventures.
I mean, Jimmy is usually kind if just a bland supporting character in most stuff today. But imagine if he was exploring the sci-if world of Metropolis and his subplots were kind of like a weird little genre-shift into Doctor Who-esque shenanigans, where he does gain powers, mutate, and time travel in weird ways. Maybe even make his association with Lois and Superman be based off his tendency to always find weird, otherworldly trouble. I think that could really work!
