I can't think of a situation in which it would be used. There are others, however, besides "spreading your wings" as you gave. If something "gives you wings", it makes you feel joyful and free - without the load of personal and world problems. It can also make you free, not just make you feel as if you were. It can be translated literally, also. If a pilot receives his official pilot's license, he usually gets to wear a pin with wings - "He got his wings today from the flight school." If you "clip somebody's wings", it means you limit their freedom. "After he came in after curfew, his parents took away the keys to the car, clipping his wings."

No. There is no such phrase in English, at least, not that I know of. But language is always evolving, so maybe you've just coined a new phrase! :))))

I don't think so... I probably wouldn't say it because nobody will have heard of it... It sounds cool though :)

I'm not sure.... what are you trying to convey Patricia? =/
