I think it's more likely we get a Gen 8 Pokemon with more Spirits bundled in with it than a Pokemon from a Gen that won't exist until 2022 at the earliest. By then, Ultimate would be four years old.It's clear that Byleth getting in was the reason why Three Houses didn't get a Spirit event like Daemon x Machina, Pokemon Sword & Shield, and Astral Chain got. I think that it's too late for Sword & Shield, but I think that a Gen 9 Pokemon could get in if Ultimate's DLC cycle lasts that long.
This DLC can't last indefinitely.
