Just some terms and ideas;
Non-conceptual awareness happens when Not-self is realised in the ever present fact of Impermanence and Suffering has ceased. It is wrong view to think Impermanence and Not-self are characteristics stuck to suffering. Awareness requires the aggregates to function.
Seeking refuge in something permanent will lead to endless suffering. Nothing is permanent. Clinging or attachment yearns permanence and sees change as suffering.
In the presence of Ignorance, Attachment and Ill-will, Impermanence is perceived as Suffering. Impermanence is not a cause of suffering but only an occasion to suffering. With Ignorance, Attachment and Ill-will removed Impermanence works cessation (Nirodha) which then continues to work happiness eternally.
To utterly destroy the aggregates would require decapitation!
It is however possible to utterly destroy clinging which changes awareness to a Not-self, Impermanent and Happy state or characteristic of the aggregates. Therefore Impermanence gives rise to evolving happiness-aggregates where a previous state again becomes suffering- or clinging-aggregates if it were to be clung to.
