Germany already has 2 UUs, so maybe the UA shouldn't be militarily focused. After all, Germany is the birthplace of so many great composers and artists and writers. Perhaps: Every culture point a city produces contributes extra great person production percentage. For instance, if a city with a temple and monument is producing 5 culture per turn, this would give it extra 5% Great Person production. Maybe even 2% per point of culture could be worked out. Either way, it would be a pretty unique UA that would acknowledge Germany's massive contributions to the arts and sciences.
