1. Download this here:

2. Put folder "SuperDuper!" into your user's Library folder and (important) customize the icon names!
3. Select "After copy" script as explained in the note.
Please give feedback if it works or if it doesn't. It works for me on OSX 10.48 with SuperDuper! version 2.1.4.

PS: you can use your own icons, for example exported from Pixadex. Pixadex is a great icon management application. Be sure to use only icons in ICNS file format.
