I’d suggest a slightly different approach: use a dual-index model.

So you get your rough data into Lucene or Solr indexA.

Then have an index-to-index writer to read from indexA, transform the data, 
then write to indexB

So indexA is “draft”, but your final application runs off of indexB.

The nice thing is you can do this as many times as needed.

Also, if you use Solr, you can leverage SolrJ and update chains to get the data 
exactly as you need it.
