Nope, that won't do it.
Take a look at how wide that 85" TV is (75" wide).
Then think... you are going to need 1/2 that distance minimum to reach a wall (37.5"). Almost an inch to short.
My original guess was off. The TV would actually come a little over 53" down each wall (assuming 90° and touching each wall).
The framing should be easy. Just build triangular frames to screw to the studs in the corner, that has a 3/4"-1" thick plywood facial mounted to the front. Then just about any arm mount should be able to reach.
[edit] Personally I would do a ceiling mount. Way quicker, easier, and more versatile.
This math seems correct using a triangle calculator. Ceiling mount I'm not sure about, would need some extensions to get it down to a suitable viewing height. The ceilings are quite high and there is seating about 15ft .
