I'm not so sure that it's out of reach. yes, trying to implement it
with gear from 1980 would be challenging. But with more modern
equipment, where the "radio" is a black box controlled by a "front
panel" or "computer" it gets easier.

The answer to this type of problem (lots of confounding variables) is
not really to go too nuts controlling things you can't control
(propagation) but to collect LOTS of data, across various sites, and
ERP levels, and then throw "Big Data" techniques at it. You'd fairly
quickly discover what a dB of ERP is worth (and probably, if the data
was kept right "I heard him but could not work him" what a dB of RCV
is worth
The challenge is collecting EIRP levels. Receive levels are easy. And
with something like skimmer, you could probably assume that any given
callsign over short time isn't changing their TX power (but they could
be pointing their beam somewhere else).
I'd bet that we could even do this with skimmer and beacon networks,
IF we knew/know what various stations were outputting at various
times. The statistical analysis could clean out the rapid propagation
differences
