Maybe they could keep the Swiss happy by giving them some extra territorium, like the other old Habsburg territoruim in Swabia.
Would that really work though? Maybe my understanding is overly stereotyped, but I had the impression that there wasn't that much of a Swiss national identity per se and it was all about your canton - so having lots more territory added onto your "country" would not be much of a compensation for your canton losing its republican rights.
