I think this is more of a users list question. It sounds like you want to have a customization system, where you can drop in a replacement for some builtin functionality?
Tapestry abounds with higher-order ways of viewing the application; what I'm saying it to institute some abstraction from class names. Don't create custom modules that overlap built-in classes exactly, create custom modules that user their own package, and use some configuration to figure out which particular class to use in a given situation. To do this seamlessly would require some minor changes to the framework ... ideally, you should be able, inside a template, to reference "MyComponent" and determine, on the fly, whether that's MyComponent from a standard module or from a custom module. Those hooks do not exist at this time, but could be introduced in your appliction, but cutting-and-pasting some code from T5.
