I'd love to see you ride through Frankfurt. Your whole idea sounds great. I thoroughly recommend using the Esterbauer Bikeline map books. They have editions for all the routes you mention, and they are simply the best.
You might also consider cycling the Camino de Santiago. Interested in Spain?
How long have you been in Linz?
