I've used 'like_class', some examples:

    <class class=".MyImage">
        <implements interface=".interfaces.IGalleryItemContained" />
        <require like_class="zope.app.file.interfaces.IImage />
    </class>

   <class class=".MySite">
        <require like_class="zope.app.folder.Folder" />
    </class>

AFAIK, 'class' zcml directives do not.  If you need to 'expose' 20
distinct classes, I think you'll require a zcml class declaration for each.
