Would you share your keymap? Curious how you're able to get all the necessary characters without making wrist-twisting layer combos. Or are you uisng chording?

Sure, QMK files are here.

It's in a bit of a rough state (one folder is for a OLED + RGB Corne r2g, and another is a currently messy adaptation for a Ferris Sweep)

The keymap itself is pretty straightforward. As rgoulter guessed it's just a modification of Miryoku (https://github.com/manna-harbour/miryoku), with some tweaks I made to keep functionally similar layers "together". E.g. the mouse key and navigation key layers are mirror images of each other. And there's a numpad layer, with nested symbols and function key layers that stack from the initial numpad layer. I also designed it to share the load between both hands as much as possible.
