Although this response is 2 yrs too late, someone in the future will have the same question and I have not seen anyone properly answer it (at least to my satisfaction).

What you can do:
1) Create a new document in Flash
2) File > import > import to stage
3) Scale all the elements so that they fit on the stage
4) File > Print > PDF > Save as Postscript
5) Give it a name and when done…
6) Open it in Illustrator! ;-p
