Hi Lewis, It sounds to me you'd be better of using Solr's very advanced DataImportHandler [1]. It can (delta) import data from your RDBMS' and offers much flexibility on how to transform entities.
Besides crawling you also mentions you'd like to push results (of what) to another structured data store. But why would you want that? Handling, processing and serving search results is done by Solr (and ES in the future) and since our entities are flat (just a document) it makes more sense to me to save documents in a document (or column) oriented DB.
