Flat screen between speakers, again.


I know this has been discussed before, but after reading most of the somewhat recent responses to similar questions I still need to pick your collective brains.
To mitigate the TV's impact, I am considering building a panel that would cover the TV when it's not in use. The panel would be a 2.5' x 4.5' diffuser or absorber. Ideally it will hang above the TV when I am watching TV and would lower down to block the TV when I am listening to music.

My question is whether this is a viable solution and, if it is, would I be better served with diffusion or absorption?

And I forgot the obvious one. All things considered it might be best to treat the room first, and then get a motorized TV lift cabinet. 
More of a visual thing.  Close your eyes when listening.  Hearing is improved without visual interference.
@tony1954  Try a test with a sheet of Owens Corning 703 fiberglass board and see what you think.
Perhaps a 5 sided box with absorption on one side and diffusion on the other side that could slip over the tv might work? Just be mindful of the cabling.
