A conventional 1915 battlecruiser develops Tiger and Renown

Would a conventional 1915-1916 British battlecruiser be an enlarged Renown or an early Admiral type?

It would likely combine Tiger's four-turret lineage with Renown-era machinery and armament in a roughly 31,000-32,000-ton design.

Four turrets in an AB-plus-aft arrangement would produce a hull that looks more like a scaled Tiger than a direct battleship adaptation. Extrapolating the steady displacement growth places the conventional successor around 31,000 tons normal load.
