i think what killed the Stargate franchise are a couple of things: 1) stopped making Stargate like it was fun, and a better version of Trek. SG-1 seemed to do a lot of stories that we saw on Trek, but far more enjoyable. They could have made Atlantis like DS-9 and.or Voyager, to a degree, and address nitpicks in a different way, shoiwing how newer Trek SHOULD have been done. 2) Stopped having likeable characters, who had some arc they could grow through. SG-1 was easy, and fulfilled that mission. Atlantis had SHepard & McKay. But Teyla & Ford were just a rough sketch, and obviously no real effort was made to develop an arc. In Universe...i didn't like most of the characters enough to care The only possibility i see with Stargate, wouldbe some kind of Teen/Pre-teen series that might also include time travel. It would need to have the FUN factor back.
