7bit is on vacation for a few weeks.
Your best bet now is to wait for the Dolch replica set to get the grey and blacks. That is going to be quite some time, but even if you had gotten in on the Round4, it would still be months of waiting.
Then all you would need is the orange WASD. There is currently (AFAIK) a leftover ROUND3 GAMER kit in orange that you could order, but the font will be different from Hashbaz's Dolch replicas. The color scheme will be what you see up there in that picture, though.
If you need help ordering from 7bit's Round4, just PM me.
