WebJul 5, 2013 · Derived tensor and shifts will land in the derived category again, so that won't help and the only hope is if hom takes values in $\mathscr{A}$. In other words, we'd need $\mathscr{A}$ to be enriched over itself or something. I'm not quite sure what that means since we might need the abelian group enrichment to coincide with the enrichment over ...
