JSF provides that functionality , only much more powerfully. Check out the spec - it's a nice separation of UI functionality & style.. you can create custom renderers to implement skinnability, not to mention render your components to other markup languages..

JSF isn't final, true, but that won't be long, and there are already implementations available (the EA version from Sun and a new alpha LGPL implementation at http://sourceforge.net/projects/myfaces/ )
JBoss has often been criticized, as has j2ee.. what specific issues do you have with JSF ?
This might prove an interesting test of the modularity aspects then, since I might create my own set of modules using JSF on top of nuke for Jboss.. :)
