Highly improbable. As mentioned, Dulio has a Longinus that can control the weather, even with the Durandal/Ex-Durandal.

Even if we take both side at their prime state, as seen with Xenovia, once you use up it's light element/Holy Power inside the Ex-Durandal, it'll take time to charge, Dulio doesn't have those weakness, he can just create ice, thunderstorms, tornado etc nonstop.
