I emailed Cherry asking for specs and the PCB footprint and they sent me the attached .PDF which i haven't seen before online.
Thanks for posting that rare, elusive datasheet!
Previously, Keebio had posted a footprint for the switch in
their Github repro.
I suspect that plate-mount Cherry MX stabiliser might work if they were mounted to the PCB. That might be worth testing ...
BTW, Kailh has announced the Kailh Choc V2 switch, which also has MX-keycap mount and similar dimensions to Cherry XMLP except that it also has clicky and tactile variants. The footprint has one of the switch pins in the same position, so a combined footprint would only need the other switch pin and possibly the pin for the click bar.
