I have not seen any advocate of Condorcet make such a suggestion, but it has been made for IRV, though not taken up by any serious IRV advocates, so far as I am aware. The weak Condorcet winner is, in my view, the political Achilles' heel of the Condorcet voting system. The corresponding political defect in IRV is that it can eliminate a Condorcet winner (whether that is common or not is irrelevant - it is possible). But we know from experience that real electors and real politicians will accept that political defect in IRV - evidence: IRV has been used for public elections for many decades in several countries. In contrast, despite having been around for about 220 years, the Condorcet voting system has not been used in any public elections anywhere, so far as I am aware. That could perhaps change if a threshold were implemented to exclude the possibility of a weak Condorcet winner AND if a SIMPLE method were agreed to break Condorcet cycles.
