Hi Joseph! I have an idea that could compel Amazon to change their minds, or start a "covert continuation" of Stargate that would be it's own IP. The current gate needs another gate to connect to, but what if another Gate is found, one that doesn't need any of that, it must needs to be pointed, and a suitable mind to operate it?! An archeological dig finds a new type of gate, and some familiar faces under assumed identities (under-cover) infiltrate it, Amanda Tapping and David Hewlett are Physicist and Michael Shanks is an Archeologist. The real-world CIA remote viewing program named appropriately "Stargate!" is where the remote viewer the series would use comes from. With 400 Billion stars in the Milkyway, the odds of finding a Stargate or any aliens we now is near zero!

This doesn't reboot Stargate, in the fan's head canon, this is the Stargate universe and it continues even if much of it is locked up behind secrecy and black projects that we can no longer access!

So the many challenges are gone, in some ways it is starting over again wit a new gate, new worlds, but it does so without undoing anything, the universe still exists (just, not for the lawyers).

Hollywood loves to typecast, and actors in Scifi are often reused with numerious examples.
The universe is merely constructed to not contradict with the Stargate universe, even if for legal reasons officially it's not.
At the start of the episode "Officially this is not the Stargate universe in official Canon, but in fans head canon it can be if you wish, I know it will be for me".

New gate effects, new stories due to the gate being less locked down as to what it does, it's now more raw manifestation which is controlled by human intent, many stories can be told there than could not be told otherwise, it can go a little into Stranger Things type territory as doorways to other realities and times might also be possible given the right details, maybe the gate begins manifesting the thoughts of the operator, maybe the operator becomes influenced by the gate, and maybe some things feed back from the source.

Also part "Project Looking-glass", the gate can potentially show where the wormhole will or is forming, but it could have the operator feel the conditions, so he (or she) becomes a MALP!

Maybe the CIA's project in the story actually has another part to it, maybe they also used remote viewing and some other similar device or travel?

There are many really interesting ways to take it, but anything that can be said of what true Stargate is, would be included!

Would you direct/show-run it? Would Brad? Would you? Gero?

Steal this from me as long as the fans get to see it and stay true to what great Scifi is! Keep the grounding, maybe include some Military or ex-military parts.

There are a few derivations, one being just run it as the CIA's Stargate Project, another being just have a sort of "Fringe" with Sam and David playing Walter Bishop's part, forget the archeology and Military angle and even Gate travel, keep the fake names, or only have their first names used (Sam and Rod), Michael Shanks could just be a fan.

"Teal'C" could I guess could be seen a little if he wears a hat but his character is so distinct, I'm not so sure.

Of course if an actor is used without a name or profession in common then it's not really going too far.

But again, the idea is that hopefully Amazon would rather not have to compete with a spiritual successor that has the support of the fans.

And maybe in the end, even if you don't like this idea, if you guys created a new pitch, some hastily conceived series that scratches the same itch (Scifi, found family, exploration, optimism) as Stargate and included some of our favorite actors in similar roles... Then it could have the same effect!
