Great suggestion if you are willing to change the plan from the original one you posted! I lived near there in Bitburg for 10 years and I would definitely suggest Trier and Luxembourg.
One other comment I have about the original iteinerary, you seem to hop around a bit. Köln and Düsseldorf are very close so I don't understand why you plan on doing Bruges in between the two. I would start in Bruges and then work my way to Düsseldorf and then on to Köln. After that I would work my way down to Mainz via Koblenz and Boppard if you want the scenic B9 route or via the Autobahn if you are in a hurry.
