What I’d like to see is a compact trackpoint module that can be snapped in place to an “off the shelf” board. Probably would have some framework that fit around a bunch of surrounding key switches to add stability. I’ve thought about trying to add one to my existing board, but it seems like it involves drilling mounting holes through the plate at least, and probably through the PCB so that the screws can be accessed.

There are a few standalone trackpoint products-- they look to be basically evaluation devices that end up with a PCB footprint the size of a mouse, 98% of which is blank, but that’s completely ill-suited to the proposed use case.
