This code will create a new document with a good size canvas for of stack of their composites. With SuperMerlin script I do not know what you will wind up with if the open document are layered and are different sizes and resolutions. He is a better scripter than me. Still it looks to me that his script will only stack the active layer from each of other open document and close them without saving them. Loosing any changes not saved in those documents.
