I think this set actually sticks with the theme pretty well. There are far too many that don't really resemble their original inspiration.
Would this set be entirely reverse dye-sub? That's probably going to turn a lot of people off. It seems like PBTfans has doubleshot ABS capability, so I'd imagine that's how this set will go.
A few things, although IDK how PBTfans structures their molds/pricing:
-Adding a tab key in the latin alphas kit would enable a base kit to cover more than one board.
-The nomad kit would benefit from a 1.75u backspace and replacing the 1.5u lock with 1.5u shift. A 1.75u shift would also be a good move.
