I just can't see them ramming through a fourth appointee in the lame duck period. For a start, there would be even more chance of some republican senators not voting to confirm. One didn't confirm Barrett this time, and there could be another Democratic senator in Georgia replacing Loeffler senator immediately rather than in January due to the special election there.
If there is any risk of not getting the appointment through, then that hands the appointment to Biden, and suddenly the advantage given by confirming Barrett is lost and we go back to a 5-4 split.
I hope you're right, although I don't see the Republicans being shy about the imposition of power.
