Can Aperture match separately imported RAW and JPEG files after the fact?

I migrated a large iPhoto library into Aperture, and many images now appear as separate RAW and JPEG duplicates because iPhoto didn’t treat RAW+JPEG as a pair. When Aperture imports directly from the camera, it can manage RAW+JPEG together and let me choose the RAW as the master. Is there a way to link or combine already imported RAW and JPEG versions in Aperture after import? If not, is it better to keep only the RAW files and let Aperture generate JPEGs when needed?

You nailed it in your last question.
The RAW file contains more information that the JPG does. This means that Aperture is (non-destructively!) going to be able to create better images, have multiple variations, and do so all non-destructively.
If you need JPG files, have Aperture generate them for you with any size or quality you desire.
If you have the RAW, there is no need to keep the JPGs around.
So, why do cameras offer both? Simple. Some applications can't read RAW files and the JPG is a fall back.

Yes—Aperture may be able to match RAW files to existing JPEGs after import, rather than keeping them as unrelated duplicates. One reported method is to import the RAWs into the same project and use the import options to bring in RAW files only and match them to existing JPEGs. This has been confirmed to work at least in some Aperture-imported libraries, though it may be less certain with items migrated from iPhoto.
If your goal is just to keep related images visually grouped, you can also use Auto-Stack to stack the RAW and JPEG taken at the same time.
In general, if you have the RAW file, you usually do not need to keep the camera-generated JPEG. RAW contains more image data and gives Aperture more flexibility for non-destructive editing and exporting JPEGs later in whatever size or quality you need. The main reason to keep JPEGs is compatibility with apps or workflows that can’t use RAW files.
