There is a script that does this, but I don't have any experience with it so I can't recommend it either way. What I did has an extra step. Basically, you edit your footage how you want it in Final Cut. Once you have it the way you want it, remove all the attributes if you added any positioning to get a rough idea for placement. Save the whole thing as XML. Open Premiere Pro, import the XML, then save the project. Then open After Effects, import the Premiere project, and then save. Ta da.
I actually JUST blogged this workflow yesterday
on my blog. :)
