Just to comment on my own post...
I don't believe index-time will be involved in this sort of functionality, as there's no way to know at index-time what 'tag groups' a given term will be in at any given time. This leads me to believe that a query request parser plugin approach might be best. Something that can receive queries when the relevant keyword is present (e.g. tag=blah) and translate the parameters into their current tag member equivalvents. Such a plugin would monitor a file (say, solr/conf/tags.conf) for changes, and reload its member table if/when the tag members change.
