Layouts
Starting from a 6.25U bar gaming layout (big spacebar is quite useful for gaming) - we went with the traditional V4N4G0N layout.
With low profile switches, stabilizer clearance needs cutouts on the PCB, limiting the potential split space options - but we were able to allow for a 2.25/1.25/2.75 split spacebar. While not as optimal as a 2.75/2.25/1.25 split, there is a split space option.
Each of the layout options will need a different plate, since low profile stabilizers are plate mounted.
