Question, since there are no characters but Oracle active/involved in the Bird of Prey set, can I still say they exist and reference "missions" they could be on, but not actually go on them?

I don't see why not. The only Bird of Prey I'll say is off limits in terms of referencing Black Canary, unless her secret identity is kept secret from the team as well. She's kinda sorta dead, as far as anyone's concerned.
