What if von Spee had brought his squadron home?

Would von Spee's squadron have been useful if it returned to Germany?

The ships would add little, but the experienced crews and von Spee himself could have had considerable value, including a possible fleet command.

The ships themselves would add little to the German fleet, but their experienced crews and commander could be valuable. A successful return through the blockade would likely have earned von Spee promotion and perhaps command in place of Scheer. His knowledge of Russia could lead him to press that campaign more quickly, giving Britain a different and potentially more difficult opponent. His escape could also damage Beatty's position and leave Hood as a possible commander of the British battlecruiser force.
