With more time and money, would the Iowa class have been redesigned to resemble Alaska more closely?
Short answerPossibly in some respects, but other design requirements and infrastructure limits would still have kept the ships distinct.
NotesA less hurried Iowa design might have looked more like Alaska in some respects. Other requirements and infrastructure limits would still have shaped the battleship. Iowa also belonged to a different ship type with different demands. Alaska's hull form could not simply be scaled up without changing the surrounding constraints.
