Actually... no. I wouldn't like to see Diamond City invaded in any game series, other than WarioWare, because I know it would be the only series I could trust to pull this kind of plot in a funny, WarioWareish way. Did you see what the Shroobs do to Hollijolli Village in Partners in Time? (and the fact there is absolutely no way for the player to restore it?)
I absolutely agree with Drumribble. I think games like that shouldn't just "invade" another franchise so hard. I like references, but this would be a bit too much.
