In this particular case (TF4), you'd have to find a spatially recorded (multi-signal) sound of a huge space ship to use in the overhead channel beds. Sounds like a job for the Auro microphone tree. I...

Keep playing that moment repeatedly while raising the crossover point to see where the "bang" stops. For the sake of your expensive speakers, everything below that point (at minimum) should go to the...

Maybe a 1st gen limitation. Would have to see how many Auro titles are released before I consider it a problem.

Can be done, but will be intimate. I would place the listeners ears about 8 feet back from the front wall, leaving 4 feet to the back wall. Can't do multiple rows, but a large couch would work nicely.

Indeed, I don't get some of the consternation. Most people should have open real estate on the ceiling for placement of overhead speakers.
