Support for Alternative Layouts
This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

I really like the crocodile key used in ISO, but that is r4 next to L-shift. https://imgur.com/a/4FEqe (if using this one, you can use this as R4, and move the current R4 key to R3 profile next to enter)
@MiTo For kobe I checked the JIS layout and even there it would be the same key as is above the enter in ANSI layout. See: https://en.wikipedia.org/wiki/Japanese_input_methods#/media/File:Surface_type_cover_JIS_keyboard_layout_blue.jpg
While you are at it, it might be nice to fix the rest to match JIS as well. The R4 key on the left should match the one next to right shift and the R1 key on the left looks a bit different (should be some utility key for all I know).
I also found your initial comment on the kobe-gaijin iso stuff ( https://www.massdrop.com/buy/massdrop-x-mito-gmk-laser-custom-keycap-set/talk/1870126 ) and I have to disagree a bit on that. There is no need to invent keys, as you can just use an ISO keyboard in your PC, hit buttons and see what the outcome is. The key next to ISO enter on R3 in my experience always produces the same character as and ANSI keyboard produces from the 1,5U key above ANSI enter key.
A crossover between the japanese layout with the European layout is simply impossible, unless you are okay with using two keycaps with the same exact symbol. Either that or you want me to 100% reproduce the JIS layout and I’ve been saying since the interest check days (that ran for over a year) that although this was worth looking at it wouldn’t be something exactly doable in the end. We are not reproducing the JIS layout because there aren’t even 10 people interested in that, these Japanese kits are merely aesthetic, for decoration, mostly for ANSI users but ISO users too. That’s the main point, the supporters of the project seem to enjoy the aesthetic and aren’t exactly worried about JIS. We can’t even have a JIS spacebar because the manufacturer simply can’t make it. The investment that would be required for that could be used to source convex 1.75u, 2.25u and 2.75u spacebars which is much more of an urgency to our community than JIS - which pretty much no one wants.
The Gaijin and Kobe kits are indeed compatible with ISO because they come with an extra R4 backslash keycap that can be combined with the short left SHIFT and if you really want, also the ‘# from Euro. I also previously said that Gaijin and Kobe must be consistent and have the same numbers of keycaps, we don’t want oddities and favorites being played... I hope you understand.
