The answer is… no. Or at least it’s extremely unlikely. Although Caamas itself has been canonized in the comic Star Wars Adventures, and an allusion to the genocidal bombardment of the world was mentioned in source material for the Age of Rebellion roleplaying game, contemporary Star Wars canon rapidly sped up the official end of the Galactic Civil War compared to the EU, ending it after the Battle of Jakku in 5ABY. And while the Imperial Remnant as a concept is currently being explored in The Mandalorian and now Ahsoka with the return of Thrawn (original recipe Thrawn, to boot), it’s never been portrayed as anywhere near the size and scope of the Remnant as it appeared previously.
Add in the fact that we’re still dealing with a loose adaptation of the Thrawn Campaign in all this, trying to set up a future version of something like this crisis in any similar way runs into the eventual formation of the First Order and then the New Republic’s shattering in the sequel trilogy. The closest current continuity has to an equivalent is the public exposure of Leia Organa as the daughter of Darth Vader in the novel Bloodlines, laying the initial shockwaves of division in the New Republic Senate that would see the secession of an internal faction to the formation of the First Order. Hell, we don’t even know what a Bothan canonically looks like yet, let alone getting them involved in a major political crisis.
That’s not to say there aren’t elements of the ideas laid out here echoed in canon, however. Mount Tantiss was recanonized in The Bad Batch as an Imperial-era hub for cloning experimentation, and likewise in The Mandalorian season three Moff Gideon was seen experimenting with clones of himself akin to what we saw with Thrawn’s almost-return. Plus, The Rise of Skywalker has the whole “secret empire hidden away to gain power at the behest of a long-thought-dead cloned leader” market cornered right now for canon, so you can’t really do it with another character again so soon.
