I'm jealous! I had planned on buying a pink keycap set and a matching HHKB (or was it the other way around?) in Japan, but couldn't find Topre keycaps anywhere. At least I was able to find the HHKB for a good price, but I still can't decide on what to do with the keycaps. EK seems to be the best alternative, but $50 shipping...
Anyway, my favourite of your pictures above is the white RF with white keys and pink modifiers. Looks the best! You should try the pink modifiers setup on the HHKB too, I think. Could look fantastic.
