A triple-turret alternative for the first Dreadnought

If the 1906 Dreadnought used triple turrets, would later British ships move toward 12-inch or 15-inch guns?

The alternative begins with 14-inch guns, using a Vickers triple-turret offer and an early Orion-style arrangement.

A Vickers triple-turret option for 14-inch guns supplies the proposed starting point. Adopting it would make triple 14-inch mountings the British dreadnought baseline. Six guns firing ahead would require superfiring turrets. Wing turrets are rejected for this hypothetical installation. An Orion-style arrangement would therefore enter the design sequence earlier.
