If you want to change RF on a live system your best bet is through DC migration (add another DC with the desired # of nodes and RF), and migrate your clients to use that DC. There is a way to boot a node and not join the ring, however I don't think it will work for new nodes (have not confirmed), also increasing RF in this way would only not be completely catastrophic if you were increasing RF to N (num nodes).
