That's certainly a viable approach. There are two notable differences 
compared to using reject:

- rejecting re-queues messages in place whereas re-publishing enqueues 
at the back

- extra logic is required to prevent message loss, i.e. depending the 
guarantees required by the application you may want to re-publish in 
confirm mode and wait for confirmation before acknowledging the original 
message.
