Consider the directivity spec. Horizontal coverage (-6dB) is 70 degrees.

I'd keep the centers horizontal, woofers at center, rotate the mid/high horns into the normal vertical position, angle them out at 67.5° with respect to each other (total included angle), and then tilt them down 25° to 30°. The vertical coverage (-6dB) is 50°. There seems little point in bouncing half of that (500 Hz to 16 kHz) off the ceiling other than to compound the problem with spurious reflections....
Currently they are set in a "v" across the center at about 30 deg. They also tilt down about 25-30deg.
The woofers are on the outside so to change them I would have to take them down and change the rigging points or swap one for the other. either way I have to take them down to do anything with them.

I will try to draw a diagram so all can understand what is happening.
