I would get 10 - 15 5 foot artificial ficus trees and 2 to 4 7 - 8 foot artificial ficus, as leafy as possible.
I would position two tall trees and enough small one behind the speakers to "hide" the green wall and a tree in front of the wood panel (projection screen?) that can be moved out of the way when necessary.
I would also place two ficus trees(tall ones, preferably) in each corner in front of the corner reflectors.
I would place one tree behind and slightly to the room center line of each speakers.
I would place one tree between the speakers and the wall absorbers to enhance diffusion of side wall reflections), one tree to each side and slightly in front of the primary listening position.
I would place at least four trees along the back wall and along the rear side walls. Maybe two a couple of feet behind the listening position.
Yeah, your room is going to look like you're on a hunting trip, but all those artificial ficus trees with their leaves act like diffusers. And they work great.
So your question is what to do about ceiling reflections. I suggest that you need to handle general room reflections first. What you have appears to me to be inadequate.
