Triple and quadruple turrets were feasible before 1914

When should triple and quadruple naval gun turrets become available in an alternate design timeline?

Triple turrets were understood by about 1908, while French quadruple-turret work was underway by 1913-1914, placing both concepts before the First World War.

Triple turrets were established technology by roughly 1908, while quadruple arrangements had entered active French design work just before the First World War. The limiting question is adoption and engineering development rather than whether the concepts existed.
