Is there a difference between the A380 and the MD12?

Contrary to your thinking, the forces that happens on a turn could mean they're actually still level to the plane floor. And there are 1g roll as well...

Depends on what kind of turn and how coordinated it is.

Was it serious? military heavy lift planes are pretty specialized in that they tend to have lots of wheels and high wings to be able to land on bad runways. Also ability to load from rear who let you air drop. 
Passenger planes tend to have center line wings and fewer wheels as they don't need air drop or bad runway capability.

Yes, modern military cargo planes usually have high wings. As you say, the main reason is to support very short landing gear and roll-on/roll-off loading.

But passenger planes usually have low wings, not mid-wings. That's because if they had mid-wings, the wing root structure would be right in the middle of the passenger cabin. With low wings, that structure is under the floor. There are some exceptions, though. https://en.wikipedia.org/wiki/Bombardier_Dash_8 https://en.wikipedia.org/wiki/British_Aerospace_146

Fighter airplanes often have mid wings but can have any of the three locations.

All normal intended turns on aircraft are meant to be coordinated. Unless you're going into a massive turbulence, entering a storm or passing through some diversion layer or something... Not that easy on those but AFAIK during training pilots are trained for coordinated ones (and automated turns are coordinated as well.)

A swimming pool is still impractical. It's not so much roll that would cause spillage, but pitch. You can't take off or land without pitching up or down and centrifugal force won't prevent your pool from spilling over.

Once the spillage starts, you get a massive transfer of weight that would be catastrophic.

I just got it from a documentary tbh. Reference is at 27:10

Apparently that's what I heard with the swimming pool thing, might not be correct.
