This of course also eliminates the current assisted classes because of Skimmer.
And if it has to be the entrant's own brain, then it eliminates dx clusters
since there someone else copies the callsign.

I don't see this as workable. One problem is that SNR depends more strongly on
the 'N' (local noise) and how good your antennas are. There are also very real
physics limits to what SNR can be achieved. You can lower SNR, but at the same
time you must increase the length of the qso and at some point it is not worth
waiting for a contest qso when others are available. We are already seeing
these limits- the most sensitive digital modes (for example WSPR) are not used
in contesting.
