I was wondering if an App can be developed in Canvas mode and embedded into a SP list/library form page (not a web page). Has anyone tried this approach? I really would like to know before I spend too much time experimenting.

Yes, you can do this. You need to set the "Enable app embedding user experience" on in the app settings.
