Could the design use larger torpedoes?

Not within this 1920 game setup: it caps the design at 20 inches, even though British and German navies historically used 24-inch torpedoes.

The game allows only 20-inch torpedoes in this design year, so the weapons cannot be enlarged further within the available rules. Germany had used 24-inch torpedoes during the First World War, and Britain was introducing weapons of that size on the Nelson class in the 1920s. The answer distinguishes a limitation of the software's technology tree from the historical equipment that a counterfactual designer could reasonably consider.
