Hey Jeff,
I’m not personally familiar with that theme, but its Events functionality seems to be something baked into the theme itself. Replacing those features with Events from Events Calendar PRO might be a complex customization, but that depends on the theme itself.
There isn’t much I can think of this from the plugin side of things – with Events Calendar, EC PRO, and its add-ons, you can customize front-end design of the calendar with custom theme templates. (This is described in greater detail here → https://theeventscalendar.com/support/documentation/events-calendar-themers-guide/)
But in regard the theme’s level of integration itself, and how to swap out its original functionality, I’d recommend contacting the Mint Themes support folk directly and seeing what their input is. That level of customization is quite a bit outside the scope of the support we can provide here, but I’ll leave this ticket open and would love to hear if you’re able to make some progress by contacting Mint Themes.
Thanks,
George
