A 1935 modernization strategy to save HMS Hood

If placed in command of HMS Hood in 1935, how could the panel keep her alive until 1946?

The strongest long-term option is an early comprehensive refit, though avoiding or changing the Denmark Strait engagement could also prevent her historical loss.

Several answers focus on keeping Hood out of the Denmark Strait action through damage, refit, or a changed deployment. Another argues that even small tactical changes could prevent the exceptionally destructive hit. Dr. Clarke's preferred route is to use foreknowledge in 1935 to secure a major modernization with new machinery, revised protection, 4.5-inch dual-purpose secondaries, and upgraded 15-inch guns. Beginning the work early would also place Hood inside the Royal Navy's wider battleship and carrier rearmament decisions. That approach preserves a useful fleet asset rather than merely hiding her from danger.
