The user management is basically divided into 2 parts, a user service that takes care of storing user properties and the interface itself (the user portlet). What you can do is just work on the portlet that communicates with the service. You wouldn't have to touch the service itself. Of course you can use the existing portlet as a start and modify the existing one. It's flexible so you can drop part of the portal without afffecting the other components. (you can disable the embedded user portlet and add your own, you could also replace the user management service if you don't like it) Output for final users rely in portlets and themes, you can keep the portal framework, add your own portlets and layout/theme without having to recompile the sources.
