Kaon physics, and particularly the decay $K\to\mu^+\mu^-$, has played a tremendous role in the history of flavor physics. In the past few decades, the B meson program has taken over as the main driving force for advancements in the field. We show, that despite the fact that $K\to\mu^+\mu^-$ has often been considered as suffering from large hadronic uncertainties, by measuring $K_L - K_S$ interference effects it can in fact lead to a very clean extraction of the CKM CP-violation parameter $\eta$, with superb theoretical precision. We estimate the feasibility of the proposed extraction in next generation Kaon experiments and demonstrate how it would serve as an independent test of the SM CKM structure.
