WI: Jane Seymour survived Edward VI's birth.

She would still likely be appointed as maid of honor to the Queen

But why? Jane has an already fully formed household. There's not a new household being made for Katherine to join.

Ladies leave the queen’s household all the time, and Katherine was still likely rather young for joining it when Jane was queen IOTL

I mean, if Mary's back in Henry's good graces, Katherine can join her household instead, which is how the other Katherine caught the King's eye. And since she's not a years-younger stepmother to her ITTL, there's going to be much less animosity between them.
