We read a lot about shading esp with many many of the LEDs out there Like Radions and Hydras. Wellllll. I have been thinking about such and how it could be got round in a simple achievable way. The idea I came up with would be a curved fixture as per the drawing below. I think I have overdone the number if LEDs, half of what I have drawn would do but hopefully you get the idea. My idea would of course require a bit more work to make it aesthetically pleasing but I think it would work, well the front curve anyway.
