RAW + JPEG automator
Aperture DOES import the jpegs as well, it just does hide them by default. Select one (or multiple) images, and select Image -> New Version from Master JPEG (also accessible via right-click). This will reveal/create a new master consisting of the jpeg which will be stacked with raw master. This however cannot be undone (ie, you cannot hide the jpeg again) except via the direct undo command.
