If Russia is made to give up Kaliningrad, who should it go to?

You should type "Königsberg". The region is called "Ostpreußen" and comprises the Kaliningrad Oblast in Russia, the Klaioeda region in Lithuania and the Warmian-Masurian Voivodeship in Poland. This is the extent of the historical region, as any Prussian irredentist must know.

Germany of course. I'd even trade it for Saxony, which should be expelled from Germany and the EU Pruss and serve as a retreat for deplorable AfD supporters.

East Prussia was a stronghold for the national conservative DVNP. Later East Prussians voted massively for... the NSDAP.

You'd better leave the borders as they stand, as ag says

Why not reinstating the Teutonic Order? Eventually it could become in a buffer state to counter the expansionism of Vladimir Putin, the Tsar of Russia. The re-created state could serve as well to the purpose of keeping the remnants of European nobility busy. Turning idle noblemen into warrior monks would receive the blessing of the Pope.
