> I feel like I am the only really hyped for the Dawn set.
I don't know where you got that impression but I, for one, like Dawn set more than Dusk.
It's just that neither looks compelling and more likely to deter than promote buying.
MG keycaps will be pretty massive individually so I think the best way to do show that is to focus on a single color, like Solarized Dark's emerald green, for all keys and use legend color to differentiate, say white legends for alpha, gray legends for modifiers.
