After Avengers Doomsday, Secret Wars and probably Battle World, what story could they possibly do after?

Knowing that they are bringing all the universes together for one movie and crashing all of them together like this, are there really any storylines they can do after? The stakes escalated to multiverse/world ending threats in nearly every movie by now, even if it was just a solo movie. it would be really hard to get back down to more grounded low level threats for a storyline after a massive multiverse story like with Doctor Doom
