So on October 10th the Sea
Lords changed to a 12x14", 28kt design. That is the decision that
doesn't make sense to me.

Several possible reasons, both the US and the UK had experience with 24
inch guns. Detail calculations on the 15 inch may have produced queries,
certainly when detailed design of the KGV was started it was decided to
reduce armament to increase protection. The US may not have been
prepared to agree to a 15 inch limit which was a calibre never used by
them. The more barrels you have the easier fire control becomes.

What can we improve (at
least in the first half of the war) with a better navy?

Well for BB less worries about destroyers and more worries about
aircraft. Twenty 4.5 would have worked better for air defence than 16
5.25. Still the easiest option is a higher priority for escort
production.

Decent close-range AA and control. A serious argument should be made
that in war accelerated progress in weapons and delivery systems is
guaranteed, and taking WW1 as an example, one could extrapolate that
aircraft speeds and sizes would grow by a multiple (speed by perhaps 2,
weight by perhaps a factor of 3 or more, depending on type), and that as
a result whatever close-range AA currently proposed would need to be
replaced by something with stopping power for such new types at at least
double the range (or more, depending on the speed and expected
robustness of attacking types). Such foresight was no doubt available in
the minds of a few far-thinking officers....



Navies in the interwar era seemed to think manuever was sufficient AA
defense.
One of the reasons the Repulse and PoW still echoes is the shock the navies
felt back then that ships couldn't manuever out of trouble. that upset a lot
of pre-war assumptions.
