I think you are describing telescopic routing. Of sorts. The easiest way
to achieve your goal is by making the communications asynchronous and
the party which has an answer to send it directly to the originator. It
won't necessarily reduce the latency though, and you would probably get
multiple answers, unless you have no redundant data in the network.
