okay, I think I have a better picture of what you want to do. Look at the example script I have below (using un-modified Apache::Registry). It prints:

MyBase HEADEhr <p>This is some text<p> <hr>MyBase FOOTER

the uri is /perl/apache.pl, as you say, we don't care about our own class name in this case, but we do setup the interitance tree. In this example we inherit from the `MyBase' package, which could also be pulled in as a module. The base class new(), header() and footer() methods are inherited, but we implement our own body() method. If this is not what you are trying to do, please explain in greater detail, example, etc.
