the old captain
the captain oldest
Now, let's imagine more 'stereotypical' nouns too get intensivity marking, so e.g. boss = boss, bosser = middle management boss, bossest = head honcho.
the old boss, the boss older, the older bosser, the bosser oldest, the boss oldest, the old bossest, etc.
I am not sure if this is realistic, but somehow it feels like the most overtly intensive noun sort of could be attracted to head-of-phrase or phrase-initial or whatever prominent position.
