I would really like to run a Commodore style set at some point, but it's more likely to be attempted with GMK. When I try that I think I may give the alphas and mods+nav break up a shot again and run it with 2 options. Have the black on darker beige alpha set, a black on white mods+nav, and a black on beige mods+nav.
That way people that have black on white set could get a black on white mods+nav for mono or a beige set with modern keys, or can go with the Commodore style, or go with an all black/beige mono set.
