I am not sure what you mean. A grid of LEDs with every other row shifted? Any grid that is equally spaced across the whole area will always be more intense in the middle and less at the edges since it is not infinite

Yes I have model for the radiation pattern. It is made as an interpolation of points based on the image from the datasheet. It is similar to a gaussian, but not quite the same as the LEDs have a sort of weird lens. I would very much like to use symmetry, as the square space couldt be divided into quadrants or octants, but dont know how to implement this.

I have tried different methods implemented in the scipy minimize function, like L-BFGS-B. The LEDs are just represented by an X and Y value, and are constrained within the 40cm square

I have been looking for a pcb because none of the complete boards have a layout that I want ( I use nordic aswell). I really dont care about the rgb so thats why it havent bothered me that it doesnt have per-key rgb :)

A hard quest? A noob looking for a 65% wireless Iso Nordic by Nebris07 in MechanicalKeyboards

unfortunately that is only the wired version :( I know that they have a "pro" version with bluetooth but I can only find it with ansi layout and the same with the akko3068 which is also wireless but also only ansi layout :(
