How sister ships could have accelerated Hood's modernization

Could Hood have received a practical partial modernization rather than a complete reconstruction?

Potentially, and surviving sister ships would probably have encouraged earlier machinery and antiaircraft improvements across the class.

Hood could have received a limited machinery replacement and stronger antiaircraft battery instead of a complete rebuild, though she would still have needed to survive Denmark Strait. Surviving Admiral-class sisters would probably have driven earlier upgrades because the navy could refine work across several related hulls. A larger class would spread design effort and provide more opportunities to apply each improvement. Class size therefore influences the pace and economics of modernization.
