IIRC, the core.properties file _is_ renamed to core.properties.unloaded or something like that.
Yeah, this is something of a pain. The inverse of "unload" is "create" but you have to know exactly how to create a core, and in SolrCloud mode that's...interesting. It's much safer to bring the Solr node down, do what you want then start it up, although not always possible.
