One more I just thought of, as a Mandalorian spin-off: Those two Republic X-Wing pilots who showed up in an episode or two in the second season. It'd be fun to see a series set around what are essentially the beat cops of the Star Wars universe.
Oh, you mean the Rangers of the New Republic series that was going to include them and Cara Dune, but then got shelved because of the actress making shady comments?
