rae-dux VS nijuni

The word I think you're looking for is splay. I haven't seen it done any keywell boards but it's on a few different flat boards like the rae dux. https://github.com/andrewjrae/rae-dux

rae-dux https://github.com/andrewjrae/rae-dux

The layout in the thumbnail is very close to one I just built (not my design), Rae-dux, if you want to save yourself a bunch of time.

2x rae-dux halves (see https://github.com/andrewjrae/rae-dux), more pics available here. $15 AUD for both.

Allow me to indroduce the Owl, yet another 5x3 + 3 keyboard ! This is a modified version of the rae-dux, the layout being the same, except with MX spacing. As for the rae-dux, it is wireless only.

So, purely out of my own needs, and since the Sweep doesn't quite cover that, I'd love a 3W6 or a Roost. Or even a Rae-dux.

There is samoklava and rae-dux, and you can look through the layouts listed in this comparison tool for more. As for ones with a trackball, the Charybdis and its nano variant come to mind.

Have you checked out Nijuni yet? It's a Corne with more stagger. https://github.com/krikun98/nijuni

Two Keyboards. One wired and one wireless, Nijuni both by u/krikun98 from this repo here:

As said, there is no space for the jst connector on corne-like boards. You can place it instead trrs jack but it limits you to wireless communication - can be done though if you plan use it exclusively like this. I'd say it's not needed, you won't change battery often anyway, you can solder the wires and have only a power switch. For example you can take a look on nijuni https://github.com/krikun98/nijuni. If you like nijuni, it would be easier to replace switch footprints to chocs than modifying corne. I can also humble brag about my own design with switch and jst - but note that it's not assembled/tested yet https://github.com/zzeneg/pica40.
