That said, there ARE Semblances which are essentially an enhanced version of abilities granted by Aura itself.

In particular:

Tock's invulnerability (enhanced version of inherent defensive ability of Aura)

Harriet's and Neon's speed (all Huntsman are already superhumanly fast)

Yang's strength boost via damage absorption (both as an extension of the protective capacity of Aura and the inherent boost to physical ability)

So having an extra powerful 'Aura Sense' is a perfectly viable Semblance.
