I was thinking if you were so inclined to try and go to the ceiling, something like this.
Long adjustable ceiling mount.

Or even a diy option with galvanized pipe and fittings for a drop down kind of thing. Or something like this.
I would also look at professional style hanging solutions as there are countless venues that have hanging speakers.
Another option could be pendant speakers, but it’s always cheaper to use what you have.
I’m not saying your Atmos experience is horrible as is. But it sure could be better!
Just trying to offer some solutions. Nice room btw.
