Every time I see something about Hood I think of an authors comment I read stating that had Hoods sisters just been completed to the same standard as Hood they would likely have all survived the Washington Treaty and gone on to serve in WWII. With four of them they would have shared the load meaning all would have been in better condition than Hood was in reality and it is more likely that they would have received major modernisations, maybe instead of those received by the QEs or Repulse and Renown. With those ships in service there wouldn't have been a need (or justification) for Nelson and Rodney and likely some of the older ships (QE or R class members) may have been retired earlier.
As stated in the video above the loss of the Battle Cruisers at Jutland had more to do with the removal of safety measures, to increase the rate of fire, than any design flaw, in fact if I recall correctly Lion's captain had not removed the flash tight doors between the magazine and the turret trunk as had been done on the battle cruisers that day, nor apparently had he prepositioned shells and charges throughout the hoists, and turrets, meaning that when Q turret was penetrated the ship was not lost. It appears the data was available to determine what had happened and why but those who gave the order that resulted in the losses didn't really want the truth to come out, end result, the RN enters WWII with the oldest average battleships and battle cruisers, instead of four of the most modern and most powerful.
It can also be postulated that had the fiction that the battles cruisers blew up because they were too weakly protected not been accepted as fact that the RN may not have become as overly concerned about magazine protection meaning no G3 and N3 designs and possibly a continuation of the more conventional four twin gun houses meaning that when the KGVs were eventually designed they would have four twin 16" (or perhaps 14 or 15" depending on treaty requirements at the time) seeing the RN better positioned to mass produce these evolutionary instead of revolutionary ships, including recycling surplus turrets from WWI battle ships into an earlier Vanguard type war emergency design.
Sorry if I have strayed too far off topic.
