Mackensens transferred to Greece

How would completed Mackensen-class ships transferred to Greece affect a later war?

They would add two useful fast capital ships to the Allied side and could serve in either the Mediterranean or North Sea.

Greece gains two fast capital ships with 13.8-inch guns, even though their ammunition differs from other Greek vessels. Their value lies in adding scarce Allied hulls rather than creating a perfectly standardized fleet. They might remain in the Mediterranean or transfer north to reinforce Britain. Against the later Scharnhorst class, their heavier guns would make them important opponents despite their First World War origins.
