Well, there is a design for this: http://zguide.zeromq.org/page:all#toc97

It uses the Binary Star pattern to create a primary-secondary backup
pair of intermediate servers. As long as they don't both crash, you'll
be fine. (So, they must run on different boxes, at least.)

Downside: it is non-trivial.
