Default Improving sheet metal esl performance

I came across this thread for improving the performance of a neo planar driver.

BG NEO 3 FR optimization

I'm guessing something similar to this, but in 2 dimensions) could improve the performance of esl panels that use sheet metal with holes drilled into it.

You could either 3d print it or cover it with a putty that dries, and create a "plow" that attaches to the hole at the top and bottom, and runs along guides on that axis. You would then do the same thing for the other axis.

I'm guessing 3d printing would be easier.

If be willing to bet that making these guides longer in some areas vs others can be used to help control directivity to some degree.

You could make the whole panel into a phase plug as well!

Does anybody really believe adding some round bars changed the red curve into the nearly perfect green curve? Or maybe I just don't understand how far-reaching the modification was.

Idk, it would be interesting if someone like zaph measures it. At the same time, if it's lowering diffraction effects, I would have guessed it would need to go around all sides of the holes.
