Amazon Aurora is not really intended to support a multi-wizard model at this time, since it does not offer the auto_increment_offset and auto_increment_increment configuration options needed for true active / active multi-machine replication. Since each Aurora cluster can replicate to and from another Aurora cluster, it is “theoretically” possible to manually configure an active / passive cluster with several masters. It is possible to configure active / active if you can use primary keys that can be guaranteed unique across the cluster (i.e. forget about automatic increment).
