I'm really glad to see this going forward, I remember spotting this thread in March, and being instantly interested simply for the MF Doom link. The Novelties are great, and the Grey on Black is something I haven't really seen on a GMK set, and I can't help myself with "stealth" looking sets.
Love the look of the novelties. Personally I'd go with Version 3, so that there's more hints of Orange than just the backspace, though I can also understand the appeal of having version 2 instead, for the consistency, especially for people who would would to use the novelties but without using the orange backspace.
Looking forward to more progress, and getting my wallet ready
