No, there's no such notion in SolrCloud. Each node that is part of a collection/shard is a replica and will handle indexing/querying. Even though you can send a request to a node containing a different collection, the request would just be forwarded to the right node and will be executed there.
That being said, do people find such a feature useful? Is aggregation expensive enough to warrant a separate box? In a distributed search, the local index is used. One'd would just be adding a couple of extra network requests if you don't have a local index.
