Danish CBs in Holstein and Oldenburg
Following the recent trend of exchanging permanent CBs with long-lasting temporary ones

I have a couple of suggestions regarding Denmark.
Danish temporary CB in Holstein:
The duchy of Schlewig, which lies north of Holstein separated by the Eider River was created in 1115 and was a hereditary fief held by the kings of Denmark. King Valdemar III Eriksen, who had been the duke of Schleswig, conferred Schleswig on his uncle, Gerhard, and granted a charter forbidding the union of Schleswig and Denmark under a single overlord. In 1386 the count of Holstein received Schleswig as a hereditary fief. His descendant, Christian I of Denmark, inherited both Schleswig and Holstein in 1460, but he was obliged to recognize the inseparability of the two territories and to affirm that they were bound to the Danish crown by a personal union only.
Even so, in the 16th century Schleswig-Holstein underwent complex and rather messy subdivisions, although theoretically the principle of the inseparability of the two duchies was not violated. The three main divisions were: (1) a ducal portion, including parts of both duchies, which was conferred on Adolphus, duke of Holstein-Gottorp, younger brother of Christian III of Denmark, and on his descendants, the dukes of Holstein-Gottorp, (2) a royal portion, including parts of both duchies, ruled directly by the Danish kings, and (3)a common portion, ruled jointly by the Danish kings and the dukes of Holstein-Gottorp.
By the Treaty of Roskilde in 1658 the Danish crown renounced its sovereignty over ducal Schleswig. The resulting quarrels between Denmark and the duke of Holstein-Gottorp were a major factor in the Northern War of 1700-1721, which ended with the dispossession of Duke Charles Frederick of Holstein-Gottorp and the union of the ducal portion of Schleswig with the Danish crown. Grand Duke Paul (later Emperor Paul I), renounced in 1773 the ducal portion of Holstein, yielding it to the Danish crown, in exchange for Oldenburg. Thus all Schleswig-Holstein were once more united under the Danish kings.
While I believe a permanent CB is more appropiate (certainly more appropiate than the CB on Estland), I understand it was removed for play balance reasons. So I guess a temporary CB will have to suffice - that 3% nationalism might even model the quarrels the Danish kings had with the Holstein-Gottorp dukes

.
Danish temporary CB on Oldenburg:
In 1448 Christian of Oldenburg was elected to be the new king of Denmark. The ancestral lands of Oldenburg were turned over by Christian to his brother Gerhard the Valiant. The Emperor Charles V gave Oldenburg as a fief to Count Anton I in 1531. The main line became extinct with the death of Count Anton Günther (1603-67). After lengthy quarrels over the succession, Christian V of Denmark became ruler of Oldenburg in 1676. In 1773, however, the Danish King Christian VII surrendered Oldenburg to the Grand Duke Paul of Russia, in consideration of the latter's renunciation of the sovereignty of Schleswig-Holstein (as mentioned above).
The claim of the Danish on Oldenburg is thus strong, which I believe should be represented by (at least) a temporary CB.
Well, just my two ducats and sorry about all these ramblings
