I was thinking something similar; perhaps a narrow (3/4 to 1") border of the brown around each square then sashing with the gray.
You could even add a brown cornerstone to the gray sashing to give a bit of that look without the extra work of making the full triple sashing with 9 Patch cornerstones.
