Nah, breakdown is breakdown, and it has to start some where (some specific, singular bond), and within the context of a field applied to an insulator, thermal contributions to Fermi energy level wrt tunneling will never be the final cause, just a helper.
Thermal energy in the lattice doesn't matter. The straw that breaks the camel's back under applied field situations will always be the propagated effects of kinetic conduction band electron energy.
