Changing weather class ingame

[DMarkwick]

Does anyone know if:

I can define two Weather classes in config, then decide ingame to change the class used to display weather? I'm guessing that the use of the Weather class (a subclass of CAWorld) is hardcoded and cannot be swapped out, but I ask in the spirit of ignorance

Not possible from what I can tell.
Weather class are tied to an overcast value by their own definition.
