John, just try to learn the hard lesson from Jim Butcher and the what happened with him and sci-fi. There was an interview with him explaining it somewhere with the last minute bait and switch what changed his show heavily and removed his input.
I know money is needed and an offer to make something in another format would be great but a show on Netflix, Amazon or Hulu would have a longer lifespan than most cable networks as they cut most shows after a season. Unless the CW gives you are good offer because if they like the show it runs from years. They do have an interest in the urban fantasy but do focus on the teenage girl demographic.
