Could an unmodified Admiral-class ship have remained useful?

Would the original Admiral-class battlecruiser design have been more useful than the modified ship?

An unchanged ship would be less useful; a larger standardised group could have supported more substantial interwar rebuilding.

The answer argues that an unmodified design would be less useful than the historical rebuilt ship. The counterfactual changes, however, if Britain completes four ships to one standard design. A homogeneous squadron would create a stronger case for applying a Renown-style reconstruction to at least one or two units. The shortcomings of the original design therefore have to be separated from the institutional value of having several comparable hulls available for interwar modernisation.
