I'd love a low profile 60 HE keyboard, because there are hardly any reasonable ones on the market so far.
There should be different layouts (ANSI, ISO,...) and a short travel distance of max 2mm.
Although there is rapid trigger/ SOCD, most people still press the key all the way down to the bottom because of the haptic feedback.
That might rule out the analog key feature, but that would probably be a different target group anyway.
There is already one low profile HE keyboard, the Nuphy Air60/75 HE, but only with the US layout and 3.3mm travel distance, which I think could be made better by you.
