If we manage to extend the "lazy core" loading from stand-alone to "lazy collection" loading in SolrCloud would that satisfy the use-case? It still doesn't allow manual unloading of the collection, but the large collection would "age out" if it was truly not used all that much. That said, I don't know if there's active work in this direction right now.
