Put the heat on them and humiliate them in public, make them dance for their oaths and seats. Pay particular attention to those from the battleground states who disputed their own elections and tried to disenfranchise their own voters, those should have much more trouble sitting in their red hot seats. Demand an apology to the American people of all of them before the oath is administered, sedition is an illegal act and unethical for a politician to even think of, much less sign his name to. Tell them they have no character and this act of cowardice proved it and them unworthy of the trust of the people. I'd make a fucking spectacle out of it, nothing sells like drama and it would be dramatic indeed, historic in fact.
Perhaps try the works of them in the house using inherent powers and then after the trial only those who tried to disenfranchise their own voters and who disputed their own elections would not be allowed to sit. Make the republicans "negotiate" for their seats, they did say they did not win them legitimately, they were on the same ballot as Trump.
