Combining the script to make Albums from a list of Version Names and the one to reveal Versions from a Preview file in the Finder, this new droplet will let you drop a series of Previews on it from the Finder and will add the originating Versions to a new Album in Aperture.

This means that you could pass JPEG Previews to a client, have them send you back the ones they want higher-res copies of, and automatically build an Album from them instead of having to manually search through Aperture for the right Versions.

You can edit the droplet by dragging it onto Script Editor.
