Hi.
No you cant add a second software initiator, the only reason for having several IQNs is when you have a IQN tied directy to an HBA adapter, in this case its a software component tied to VMkernel with no hardware tied directly to it.
You will get full redundency with port binding if you set up the physical adapters correct
For example.
vSwitch1
Vmnic1, Vmnic2
Port Group 1- iSCSI-1
Port Group 2- iSCSI-2
Load Balancing policy for the Port Groups
iSCSI-1
Active - Vmnic1
Inactive - Vmnic2
iSCSI-2
Active - Vmnic2
Inactive - Vmnic1
Then just add the portgroups to iSCSI port binding and specify all storage controller IPs under either dynamic discovery or static discovery and you will have full redundency too all data paths.
Same rules applies to both physical and nested setups, no difference
