Is a 9.2-inch-gun cruiser more likely in this timeline, perhaps as a secondary Dominion flagship?
Short answerPossibly, especially as a Hawkins-class equivalent, but this scenario follows the battlecruiser route instead of combining both alternatives.
NotesA 9.2-inch-gun cruiser could serve as a secondary flagship for Dominion and distant-station forces. This counterfactual follows the historical family of battlecruiser construction instead of adopting that alternative. The more likely later opening is the role filled historically by the Hawkins class, replacing its 7.5-inch battery with 9.2-inch guns. The cruiser remains a plausible branch outside the scenario's central battlecruiser argument.
