You could inject a new FetchSubPhase by a custom search plugin :

https://github.com/elastic/elasticsearch/blob/b84a6ed5e6fc1e057f8c0f4d6758a80b3d2a51fd/server/src/main/java/org/elasticsearch/plugins/SearchPlugin.java#L84

However, to make outbound calls - you will need to modify jvm security policy.
