I wonder if something like the following would work:

   (:pagelist group=Class* list=normal fmt=hierarchy:)

The wildcard would manage to get all of the pages in Class and
its "subgroups" -- so after that it's just a matter of 
displaying the pages in a useful sequence, which could be
done somewhat handily in a custom routine (triggered by the
'fmt=hierarchy' parameter).

I think that wildcards handles the case of searching and pagelist
generation that you've described above.  As far as page renames
are concerned, I think that in practice it ends up being the
same amount of work for both a hierarchical and flat naming scheme.
(I know this last point isn't at all intuitive, but all of my
thought experiments on the topic have pretty much come to this
conclusion.)
