Need to tilt terrain on runtime

Is it possible to tilt/rotate terrain at runtime?
I am making cutscenes in my project and i want to cheat the camera angle a little bit and easiest way to do so would be to slightly tilt my terrain at runtime for the duration of the cut so i can see more sky and bg… But it seems like rotating terrain in unity is not possible…

at this stage i am only using terrain to render trees and grass due to performance problems on android. still when i rotate the whole thing even if its set to lightmap static it only moves up and down rather then rotating/tilting. If anybody knows a way please let me know.
