I have not used ETL but the wikipedia definition of it does not
suggest it is very appropriate for what you want to do [1].
However it is not clear to me what you are wanting to do. Are you
asking about how to add a web service to an existing app, or how to
consume an existing web service? If it is the latter then I don't see
what the question has to do with Rails as the service is already
defined.

As a secondary point why don't you just add the new reports to the existing app?
