Could an autoloader explain Agincourt's design mystery?

Could an early autoloader have been the mysterious feature of the aborted Agincourt design?

It could explain added complexity, but it seems unlikely because serious Royal Navy autoloader work appears later, in the 1920s and 1930s.

An autoloader could account for unusual complexity in the proposed ship, although that possibility has less support than the other explanations. The cancellation can be explained by wartime expectations that long-lead construction would finish too late, while viable British autoloader work belongs more convincingly to the interwar period.
