Could a taller-hangar Indomitable design have lasted after the war?

How long might an Indomitable design with a single tall hangar have lasted after the war?

No date is given; a larger class would have been more likely to remain in service longer.

The answer does not offer a fixed retirement date. It makes the number of ships built to the design the deciding condition: a larger class would be more likely to remain in service longer. The brief exchange leaves the design's exact postwar service life unresolved.
