The Galactus Cloud didn't do anything... It was a cheap way to end the movie.Again there is no way to tell what this Galactus was capable off.
Storm, while powerful, doesn't have near the "ummph" to take on what was presented in the FF/SS movie. She could likely mitigate some aspects of it's initial encounter, in a localized area, but she soon would find herself overwhelmed. As part of a Team, however, of powerful beings (Thor, Dr. Strange in better times, and similar), her abilities could aid in circumventing many effects that were indicated in the movie, though it still would be a very, very rough ride, and the wins would still be on the "losing end"...
