For ages (years, probably) I'd lapse into clarinet fingering playing sax if I was stressed at all. Especially if I was playing a piece not specifically written for sax with notes below Bb in it. I'm not at all sure I'd ever manage to be an effective doubler.
In the sax quartet I used to play in the tenor player and myself were really clarinettists we both regularly suffered from emergency clarinet fingering moments.
Re the very high notes on bass - take a look at the plate on the 1st LH finger - it should have a little hole in it for the notes above the C hold it down but don't cover the hole. I can get a full 4 octaves out of my low C bass, but I don't see much point in bass that high.....it's that bottom regisiter I have it for

I do sometimes find the vibration when playing the low notes a bit disturbing. I will occaisionally either double lip or just lift my teeth from the mouthpiece if playing very loud low notes.
Be careful - a bass will start to seem way more appealing than an A - there are more wind bands wanting a bass clarinet than orchestras looking for someone with a pair

I think maybe something went wrong with your post jojo

Been playing it again tonight. It does take a whole lot of puff

Wish me luck for tomorrow

You may find your tone on Bb improves through playing bass just through having got used to shifting much more air through the instrument.
Have fun tomorrow
