Oh yea, the FWL16 keyboards could be great in multiple models. I know I’d love to see that.
People have talked about methods to create more vertical space, but Iirc it was in the context of making room for off-the-shelf mechanical keys. And I think almost all of it was centered around the FWL16. But the same or similar ideas could potentially work in the FWL13. One thought was adding shims under the hinges to raise them, and the screen along with. 3d printing a new hinge cover and bezel or new input deck.
Maybe it was in one of the ortholinear threads. community.frame.work/t/ortholinear-keyboard-option/3321
