If by Wisdom, you refer to the knowledge of the actual condition, then you are saying that light can be obscured by darkness or enlightened knowledge can be obscured by misknowledge. If your Wisdom refers to something else, then it is merely mundane wisdom and is of no consequence. Calling that Wisdom becomes an obfuscation.
Wisdom (jñāna, yeshe) is the basis.
Rigpa/sherab is knowledge of one's actual condition i.e. the basis.
Anyway, you can use whatever word you want for ye shes, timeless awakening, pristine cognition blah blah blah.
These are all just signifiers anyway and of no real consequence.
Wisdom (insert favorite jargon here i.e. Jñāna, God, Brahmin, Yeshe, George, Turiyatva etc.) is a state, i.e. the basis (sthana). It is unaffected by either knowledge or ignorance, cannot be improved or damaged, is permanent, self-originated, empty, radiant, etc., has the three kāyas, everyone possesses it, and so on -- you know the drill.
Anyway, I am tired of debating people -- -suit yourself.
