I ask for forgiveness if this was asked and answered before.
Doesn't consciousness already includes attention to something, awareness of?
So one cant cultivate what already is inherently there. But if by sati we mean remembrance of Dhamma*, then that is something beneficial we can do.
*Example: If one sees attractive person, one should remember "mindfulness of the body" (kāyagatāsati).
If we look the context in which sati occurs, it suggests far more than mere bare awareness.
