iSCSI multipath

I have my Dell MD3200i setup per the Dell docs with the following configuration on the controller ports:

Controller 1:
Port 1: 192.168.130.101
Port 2: 192.168.131.101
Port 3: 192.168.132.101
Port 4: 192.168.133.101

Controller 2:
Port 1: 192.168.130.102
Port 2: 192.168.131.102
Port 3: 192.168.132.102
Port 4: 192.168.133.102

However all the traffic is being passed on one specific vlan, not 4. It works this way but I am looking to simplify this if possible. Would there be any negative side effects to changing the setup to be this instead:

Controller 1:
Port 1: 192.168.130.1
Port 2: 192.168.130.2
Port 3: 192.168.130.3
Port 4: 192.168.130.4

Controller 2:
Port 1: 192.168.130.5
Port 2: 192.168.130.6
Port 3: 192.168.130.7
Port 4: 192.168.130.8

Doing so would greatly simplify my setup and make more sense. Is there any reason not to do it this way?
