That's exactly the direction I was thinking.

Or you might be able to cut a notch where the PCMCIA connector interferes
or put in a shallower dado for it, though the latter would take extra
time in the laser.

That's a consideration.
It also occurs to me that if the design has the PCB held at one level,
with the connectors all just mounted to the PCB, then the Z instability
doesn't make that much difference. Just account for it so the top
doesn't collapse down making the ports unusable and be done with. Most
users are probably unlikely to be carrying it from desert to wet
rainforest too often. Recommend "firm hand tight" for the screws, and
few if any will notice a problem.
