if you implement the synchronisation between these 2 applications, yes

... se 1. and 3.

>(as though it forms a single index, search results should consider the documents in both
the indexes) from the WebApplication.  How to go about implementing this, using Lucene API

If yor requirements allow you to create to independent indices, than you 
can use the MultiSearcher to search in both indices.
Maybe this will be the most cost effective solution in your case,
