Thinking about a common blade for ATLAS L0MDT and CMS IT-DTC.

First, looking at low stack height connectors, but not Z-ray. (See Samtec guide) Samtec families with low stack heights:

Family Series Stack Height Notes
Sea-Ray LPAM/LPAF 4mm
Edge Rate EDM6/EDF6 5mm
Q Series QTH/QSH 5mm? 28 Gbps+, pairs, power
QTE/QSE 5mm 25A GND plane
Ultra-Micro EDM6/EDF6 5mm
ST4/SSR 4mm

Below is a figure with dimensions excerpted from the ATCA standard.

This gives us about 15.7mm above a mezzanine board for components.
