If there's an R3 run, I would sell my soul for a kit with a blue number row, for the space cadet look on 60%'ers and other boards without a F-key row, especially if there was also a 1.25u black-on-blue COMPOSE and a 2.25u FUNCTION. And/or perhaps convex 2.25u and 2.75u spacebars
Since I doubt anybody would even want my soul, I guess I'd just pay money, though.
