I think your use case can be managed without altering the existing processing model for topic maps. Locating all topics having a base name containing a given scope is relatively simple conceptually, and while I've not yet done this myself it shouldn't be difficult to code either. It could actually be done using XPath if the topic map was "consistent" [1], ie., one topic per subject and no further merging to be performed.
