What would happen if you hacked Forecast onto a Pokemon other than Castform?

Question

Say it uses Sunny Day, would it become Fire type?

Answer 1

Nothing

This Ability has no effect on Pokémon other than Castform.

Bulbapedia

As well as this if you Skill Swap/ Trace Forecast with another Pokemon. Nothing will happen.
