I don't really understand the connection, since French has plural adjectives and English doesn't. And in my head, that was also why the above list is the way it is- English doesn't have plural adjectives, so of course you denote the plural through the noun. If it were French, it would be more like attornies generals. Not to mention that some adjectives go before the noun in French, and for those, it's still both the adjective and the noun being made plural at the same time. I'm not a linguist, and also neither native in English nor French, can you explain?
