No problem, happy to help! For scooping, do you mean pitch bends? Those are pretty doable for just about everyone, but in fast succession or a glissando (like clarinet in Rhapsody in Blue, for example), they don't really work and may not be as defined as you want, depending on the oboist.

Prof. oboist here - the only thing that sticks out to me is the tremolo - I'm guessing you're wanting a flutter tongue here? Not all oboists can do that and it's not necessarily something that's regularly taught, even in extended techniques. I would say offer an option for a timbre trill for a similar effect, in case the oboist can't flutter tongue. There's a great book for contemporary oboe techniques by Libby Van Cleve, called "Oboe Unbound: Contemporary Techniques," if that's your kind of thing. Hope this helps!
