Question for any Japanese speakers/readers here (secondary keycap legends)

[Special K]

I'm working on an IC for a keycap set, GMK "The Matrix" (https://geekhack.org/index.php?topic=78931.0, yes I know it was started a long time ago) that will feature Japanese Katakana characters as secondary legends and have a question for any Japanese speakers/readers here:

Is there any particular mapping of the Katakana characters to the standard alphanumeric characters on a US keyboard that would make sense?  I was looking at the character set here: https://en.wikipedia.org/wiki/Katakana and it looks like multiple characters have the same starting consonant sound, making a 1:1 mapping between the Katakana characters and US alphanumeric characters impossible.  For comparison, the GMK Laser set used Hiragana characters as secondary legends:

Is there any rhyme or reason as to how those mappings were chosen?  I couldn't find an explanation in the set description and contacted that set's creator but never received a reply.

This is primarily an aesthetic choice, but I'd like to see if there's any particular layout that makes sense before paying for renders.

u can't match based on sounds. the hiragana in the laser set is just what the standard is, it's almost always ordered that way across all JIS keyboards.

if you wanted to make a katakana set, it would follow the exact same order, just with the different alphabet.

Would you be able to tell me the names of the characters circled in green below:



Some of those look like symbols that aren't part of the standard character set, but I'm not sure on that.

top left extends vowel sound

bottom right 3 are comma, period, and the solid dot is punctuation for separating characters

bottom left are brackets and dakuten and handakuten

Does this mapping look correct:

at a quick glance everything looks good!

I've always just typed with the romanji, never used the other keyboard.
