I’d go take a look at blue alert’s recent sales graph with a focus on the amount sold prior to extras being purchased.
https://geekhack.org/index.php?topic=123626.msg3194635#msg3194635400ish base kits sold, at the absolute most trusted USA vendor. Extension sells half, and that extension has novelties which is some people’s interest in it. Your MOQ is 250 for base because custom colors and 100 for child kits.
International kit sold…17? Maybe 18 kits. Vendors had to buy that to 50. Those kits are usually sold without profit. A UK kit is going to be hard to sell 50, and even harder because low MOQ kits are priced high.
With these constraints: what would base/novs/accents look like if this were all that ran? The accent kit as is will approach 40$. Are there keys that could be cut to get it to 30?
Neat design, I’d buy. But the market right now is pretty limited for GBs, and GMK child kit pricing is rough at low MOQ, and that’s gonna change kitting decisions.
