The noun sense of female well precedes (going back to its Latin roots) the adjectival sense of the word. [1] The adjectival sense came from the noun, the exact reverse of what you are saying.
And this pattern of adjectives coming from nouns (e.g. leafy, greasy, beautiful, harmful, dangerous, adventurous) is common, while the reverse is not (I'm hard put to think of even one example). So what you are saying here is a nonsense, with no scholarly basis to it.
