Can I replicate both directions between two HANA nodes?

In light of SAP note 1681092, and it's support for multiple production HANA DB's on one system can I make a two DB solution on two scale up nodes where node A replicates DB1 to node B, and node B replicated DB2 to node A? So long as I ensure that memory limits are properly configured for each of the instances?

Like this:

HANA Appliance 1 HANA Appliance 2

PRD1 instance ------ HANA PRD1 replication --> Replicated PRD1

Replicated PRD2 <----- HANA PRD2 replication---- PRD2 instance
