I love Munich but I'd minimize the time in Frankfurt; from FRA airport, you could go directly to Mainz and the stretch of Rhein with the castles. Düsseldorf is lovely. You might want to consider going to a wine village briefly; the town of Rudesheim is one of the easier and more convenient ones to visit but the Mosel valley is nice too, with good scenery.
