Pinephone keyboard has extra GPIO exposed on PCB (on my request, because I had this mod on mind, early on) so that this is doable, and I made sure the firmware is safely flashable in field: https://xnux.eu/pinephone-keyboard/ so that it can be extended to support this.
That would add 6 different or 2x3 symmetric modifier keys to the bottom (3 for each hand) in addition to what's on top, and would make the keyboard much more usable for thumb typing.
Why waste 2-4 fingers that are usually resting on the bottom?

I have to find some time to attempt the mod. :)
