I know it's an alien concept to most of us (because, let's face it - we know everything...) but when starting a new instrument it's possibly a good idea to get some help. Need not be a formal teacher, maybe just someone who's a good player of that particular instrument and is prepared to impart some knowledge.
As a sax/clari player, I taught myself flute (or so I thought...) then had to go 'back to basics' and relearn about flute embouchure all over again. I think the same might have happened with soprano, had I not had years of clarinet experience - some of which was helpful, some definitely not !
So JazzItUp, if you can, seek out a wise man who plays soprano the way you'd like to play it...... It may save you hours/days/weeks of frustration. He/she (sorry, I should have said "wise person"..) will also be able to play your setup, and show you what it can potentially do - just in case you have an unsuitable combination.
