  Ascribed as $\rho\rho$ and $K^* \bar{K}^*$ molecular states, respectively,
iso-scalar $f_0(1500)$ and $f_0(1710)$ states are expected to have iso-vector
partners, potentially identified as $a_0(1450)$ and $a_0(1710)$. The predicted
dominant decay modes for these two $a_0$ resonances are $a_0(1450) \to
\omega\pi\pi$ and $a_0(1710) \to \omega\pi\pi,\,\phi\pi\pi$. We estimate cross
sections for two-photon production of these four resonances within the hadronic
molecular picture, and demonstrate that SuperKEKB's luminosity is sufficient
for their observation and more precise parameter measurements.
