Why not just make a copy (or clone) of your original file? That approach greatly minimizes the amount of work needed to get what you want.
If you must export the data, why not export it as a filemaker file? That way you can export the containers as well.
You should be able to open a file, enter layout mode, copy all the objects and then open a second file, enter layout mode and paste the copied objects. The issues you encounter are detail specific, the table occurrence of the new layout should have the same exact name as that of the original layout, the field names must also match. You may need to set up different layout parts to the exact size of the original layout before the copy/paste...
