Instance MC from one timeline into another

Is it possible to get an instance from inside a movie clip and copy it to the stage? I realize that there are several ways to do something similar but it would be very convenient for the project I am working on. It would be most convenient to duplicateMovieClip from a MC to the stage.

Can I access the library of a loaded swf? I could also solve the issue if I could attachMovie from the library of that loaded swf.

I can’t really just loadMovie an external swf of the MC I want to instance because I can’t wait for it to load during runtime (it’s a game).

Any suggestions are appreciated, thank you!
