A mixed-propulsion warship analogy applied to the Venator

How would a Venator-class Star Destroyer change if its designers followed the mixed-propulsion historical-warship analogy in the prompt?

The analogy suggests more guns at the cost of flight-deck space, although a proposal for multiple hangar openings is challenged because the Venator already has them.

The proposed turbine and triple-expansion analogy does not translate literally into Star Wars propulsion. Applying its broader design choices to a Venator suggests sacrificing some flight-deck space for heavier guns. One suggestion is to divide aircraft access among several smaller openings, although the reply points out that the fictional ship already has several hangar entrances. A heavy laser artillery piece placed in a hangar on ships under General Skywalker's command was a local modification, not the class standard. Aviation access and improvised armament therefore need to be distinguished from the underlying design.
