Khaannn,
Since you've already dealt with GMK...why don't you start your own GB? Maybe see if someone wants to design it with you and get one going....I think the only issues is there have been a flood of them lately...
A basic set costs 15.000 euros with a rough calculation, let's say 20.000 euros with some satisfactory extras
I would probably just separate things and approach it as alphas+modifiers, get some risk-free alphas like white on black, dolch alphas, black on white etc.
Then probably get separate modifiers made similar to billnye's - this puts me around 100.000 euros max, a significant investment, but it enables buyers to mix and match alphas and modifiers to their liking freely
The real challenge is the business and taxing part, I hate the concept of an official taxed business, so the idea ends here, it wouldn't be easy to do all these and do it on a personal scale, I try to influence Originative instead, which pretty much does this, the next set of Dolch's are going to include a 1.75 R3 Control for example (also 1.25 blanks), it's a small victory but a victory
Also, again comparatively, on a personal/selfish scale, I achieved this for myself by spending <<2000 euros, I have a lot of unique modifiers, blanks, dolch alphas, bumped F/J's on the way, so extending the existing sets on the market is always much much easier
I think it should even be a thing, GB leaders could allow small groups to add custom keys, and the GB leader could handle the payment etc. - this way no one would become upset, they either would pay or accept the situation
This is much more doable with SP, a unique keycap is $100, and producing 10 probably makes it $12 x 10 or something, $50-$60 is a small amount to pay for some keycaps that will make a set perfect for you (each absurd layout generally has 5-6 supporters at least, probably 50-60 for alternative homing keys)
As another unrelated note, I think these extra keycap ideas are falsely dismissed by individuals, I see a lot of people that spend $100-200's on multiple keycap sets, yet a lot of people shy away from paying $100-200 for custom keycaps that they need - paying $100-200 for one set and $400-500 for custom keycaps makes a bit more sense to me, because no matter how many $100-200's you drop on multiple sets, you usually can't get exactly what you want (my DSA adventure is a physical manifestation of this, I had 6-7 sets at least but didn't have what I want, ended up selling them all, now with GMK's, I have what I want, I will soon move on after an exact year of a keyboard/cap journey)
