Why a restored High Seas Fleet would not solve German naval weakness

Would pristine ships from the High Seas Fleet be useful if they reappeared in Germany in 1939?

Some could be rebuilt, but crewing and modernization costs plus a major British response would prevent them from transforming Germany's naval position.

The scenario gives Germany intact ships from the scuttled High Seas Fleet shortly before the Second World War. Only the strongest König and Derfflinger types are considered worth retaining, and even those would require extensive rebuilding and new ammunition arrangements. Older ships could be transferred abroad, but Germany still faces the same shortages of trained crews, fuel, and supporting infrastructure. Britain would respond by accelerating King George V and Lion construction rather than pausing its own programs, preserving the strategic imbalance.
