The thing is that WELS and LCMS would not be welcome there. There are synods that we are in communion with in Germany and Scandanavia, but they are restricted by the state (the state churchs don’t like them).
It may be the Orthodox who have the best shot.
Ah yes, the damned state rules for registration. Yes, the Orthodox may have the best shot. Now we got to get them to actively evangelize in Germania and Scandanavia!
