I can only find plates with such stud dimensions but not in brick form. The only way to accomplish it by stacking 3 plates but that is both a waste of bricks as well as creating those regular notch gaps along the side which is an unwanted visual.
Just the DSG one above [it has pin-holes annoyingly]. The only other option is to go to a different radius, such as 4 studs, that will give you many more brick, panel and plate options.

> Yes but in white?
As I said, only in dark grey.
