The functionality you describe are available (mostly) with the Records Management module for DM. Without writing your own custom extensions this functionality is not available in DM. Does WCM ever require this kind of functionality?
What've we've done in couple of projects was to use both DM and WCM. The document lifecycle will be handled by DM including publication with WCM. This will give you better control of your digital assets such as documents, images, videos, etc.
Something to think about. Ping us if you want to talk through the options.
