Measurements of anisotropic flow in relativistic heavy-ions have been shown to be highly sensitive to nuclear structure. With a proposed $^{16}$O$^{16}$O run at the Large Hadron Collider and RHIC we study the potential for finding $\alpha$-clustering in $^{16}$O. Here we couple the iEBE-VISHNU event-by-event hydrodynamic package with $^{16}$O nucleonic configurations from ab initio nuclear lattice effective field theory simulations. The transport model parameters used were obtained from a state-of-the-art Bayesian analysis in p-Pb and Pb-Pb collisions. We argue for two clear signals of $\alpha$-clustering at both RHIC and LHC energies: first, that $c_2\!\left\lbrace 4 \right\rbrace$ should experience a sign change at ∼20% centrality with $\alpha$-clustering (in contrast to ~50% using a Woods-Saxon), and second, that the centrality dependence of $v_n\!\left\lbrace 2 \right\rbrace$ should differ dramatically between the two beam energies.
