WS2811 + Monome

Has anyone here considered combining the WS2811 w/ the grid?

(it’s the major chip behind the neopixels, full rgb led control, 3 line interface)

Neopixels themselves might be too big, but you can get the driver chip on its own, and mount it on the bottom of the PCB.

So yeah, easy full RGB grid. Is this something people would be interested in? Has it been discussed before? I hate doing something someone else has already done.
