I'd say Lower Decks feels like DS9 successor, they had DS9, Kira, Quark, and the Cerritos has the Bajoran security chief.
And I believe while Avery Brooks is retired from live action acting, he still does voice work, as it doesn't interfere with his true passion of teaching,so an appearance on LD is more likely.
Of course there is still a possible DS9 connectioned show in the feature say Star Fleet Academy (O'Brian), Section 31 (Bashir/Garrek), Star Trek Anthology, or a possible Enterprise F show with Captain Hanson (Seven) with some kind of DS9 tie in, like a new Dax host.
