you may be able to lower your screen, and mount a VP150 above the screen, as the second row will not need to have a clear view of the VP150 anymore, this would save you from doing further construction on your screen.

A VP150 doesn't take up much room, and it can actually be mounted "over" your black frame, and when you look at it from below, it won't even look like it has been mounted over, as long as the projector as a clear view of the top of the screen for 16:9 material, you're good to go!
