That would conflict with the proposal rules, as the MD5 is rather fixed.
MD5 would easily break in case a vendor uses the flexibility build into 
the current set of tags. How would a DVI 128 bit and a HDMI 256 bit EDID 
from the same monitor with the same characteristics compare. Do you plan 
to embed both versions of EDID block inside the same profile?

Lookup of profiles with the described meta tag inside is in Oyranos 
rather fast.
