If these cunts actually knew ANYTHING about what the fans want it's that we want something far more akin to the old Trek. None of this gritty grim shit that they've been pushing. We want to see mankind at our best, especially after recent years when we've seen ourselves at our worst. We want hope for the future, not despair. And that's all they're giving us.
Now if you let ME make a Trek show? I'd set it 20-30 years after the Dominion war. Try to cover some of the shit that's happened since then like the rehabilitation of the Vorta and Jem'Hadar. I'd completely ignore the idea of Romulus being destroyed because for fucks sake we have the technology to figure out that a star is about to go supernova and I doubt the Romulans aren't monitoring their own fucking sun. I would try to assemble a cast of fairly diverse characters like DS9 had because we really don't see as many aliens on federation starships as we should. TNG had worf. That's basically it for actual aliens. Deanna Troi doesn't fucking count.
I'd try to show a fairly positive view of things. Like in the aftermath of the Dominion War the Romulans have become a staunch ally of the federation, and the Klingons are looking ready to join outright.
I would indeed try to do a few cameos of actors who are still alive, and offer some explanation as to why we never see those who have died. For instance Odo, he can't come back because Rene Auberjonois died. How do we explain that? Well the Changelings, even under Odo's guidance, just don't feel ready to rejoin the galaxy. They believe it would be best to wait until it's been long enough that the Dominion is a distant memory. Doesn't stop us from potentially having a changeling tho since there are still The One Hundred.
Quark can make an appearance. Maybe we find out he sold his bar and now owns his own orbital casino and resort. Rom is Nagus so we can also definitely see him on occasion. Perhaps Garak has managed to gain some sort of high ranking office in the new Cardassian government. We can even have an episode where we see old Ben Sisko, having returned from his time with the Prophets and returned to settle down on Bajor as a sort of spiritual leader. Maybe Cassidy Yates waited for him and he got his happily ever after after all. Maybe we see Jake. Maybe we see Dax and Julian. Maybe we see Worf and Martok. We could see Janeway, Harry Kim, Tom Paris, who the fuck ever.
One of the biggest problems I'm seeing with the new Trek is that it's a lot less episodic. There's this insistence that everything must be part of some overarching plot, like the Romulan-Synth shit. Star Trek is always at it's best when you free yourself up to do whatever the fuck you want, and sticking to a set story for an entire season with no room to breathe is the best way to fuck up Trek.
