Are there mods for these keys for Colemak variants, Dvorak varients and Workman etc. layouts? Will it be too expensive if new mods are needed to produce these keys?
It helps the sale to add more keys. But I think OP should get quotes about the MOQs and prices, and check whether it will be too expensive to add these keys for a practical run. The colevrak kit usually just sells a few dozens of units. I'm afraid it's not easy for us to reach 150 or 250 MOQ like many GMK keysets did. Even if it's possible for us to run it at MOQ 50 for price $60/kit (refer to recent GMK Oblivion R2). But when more keys are added, there is a risk that the price goes too high and then hurts the sale.
I would like to support but I don't feel confident it would work out given how GMK keysets run. It's out of this thread, but I think it's more practical to make some Colemak kit for some keyset with low MOQ and proper price, e.g., SP SA Hyperfuse, etc. So that we Colevrak users could have more choices on different keyset themes rather than being limited to several popular GBs(most on Drop) with Colevrak support.
