In Tchaikovsky's Romeo and Juliet overture, there's a key signature change to F minor in middle of a score.
The clarinet in A changes key signature to B major, but because the clarinet is A, the real key signature is G# major. That doesn't exist in MuseScore, and custom key signature doesn't help.

Probably not, I don't think we support non-standard key signatures like G# no matter what. Not sure what is meant about custom key signatures not helping though, that seems like the answer if you really truly want this. I'd suggest you - and more importantly, the poor clarinet forced to read this - would not.

In my Romeo and Juliet score (Hawkes Pocket Scores), the clarinet part has 5 sharps at rehearsal mark 2 when the concert pitch instruments have 4 flats - Ab not G#. Similarly, after rehearsal mark 19 it has 4 sharps while the concert pitch instruments have 5 flats. This is what I would expect.
