CMF tools are grabbed using acquisition.  Therefore, you should be able
simply to delete the portal_catalog in each sub-portal, and reindex your
content using the tabs on the root catalog.  Everything should work as
you describe.  (But I've not tried this and I may have forgotten
something obvious).
