Me complaining about this aside, they're never going to do Martin Gero's Stargate--it's clear as day.
That said, the
#SaveStargate campaign has undoubtedly been heard loud and clear. If there's any hope left, it's that we've at least convinced whoever is spearheading the writing team and new showrunners to be faithful to what the core of Stargate is.
I wouldn't count "in the existing canon" as an impossibility, but let's be reminded that in new Trek, they tried to retcon things into the old canon to force their own (very) unique take on Trek to satisfy the old guard. It did get a few on board, but it also divided the fandom sharply, particularly along political lines, as the publicity and showrunners were exclusively catering to one group of people.
This is not what we need in Stargate, which has somehow always catered to everyone. How is that possible, then? Because it knew what it was and was made for people who love military sci-fi and wanted a deep experience.
The opposite is also true: make someone for everyone, and you please almost no one.
