I mean, if they make a dragon themed expansion its gonna be quite hard to exclude the void from it.
They could just do a small LvV side-plot and simply keep the overarching plot about the dragons.
We get the dragon isles, it contains an important titan facility - maybe Azeroths soul chamber - and have the main villains be a refurbished TH, lead by Xal'atath or someone else and the chromatic dragonflight (edit: and/or the infinites, forgot about those)
Have a subplot about the Lightforged picking up arms, maybe have a new Naaru or 2 come visit with some new characters.
They help us with the Xal'atath problem, but they never become the main focus as to avoid another BfA.
Expansion ends, TH defeated (again), dragonflights are supercharged or something idk, Azeroths soul wasn't hijacked, etc.
11.0 starts and the Lights forces arrive on Azeroth and demand we join them, starting another conflict with the Light as the enemy.
