Can I use 8 gb Fibre Channel for storage iscsi traffic and 1 GB for standby

Environment

Version - Vmware: ESXi 4.1

-Host: 360 g-7 DL, 2 x 1 GB quad port NIC, 1 dual CF 8 gb HBAS

-Storage: EMC VNX 5300 host FC HBAS are directly connected to the San

Background

We currently have a 1 GB LAN (Cisco 3750 battery) \storage (san is LeftHand 4500) network that will not provide the e/s, we need for our SQL server due to a limitation of the NMP esxi a company proposes a new solution of storage for us.

Overview of storage design:

2, 1 GB of NIC quad by the host in support of our networks (VM\MGMT, vMotion, DMZ, iSCSI).  Add a dual port 8 gb FC HBAS on each host for storage.  I then path redundancy but not the redundancy of HBA cards.  Can I use the existing 2, 1 GB iscsi NIC as the standby for the FC HBA just to limp along until I vMotion, virtual machine to sql server on a server that has a FC HBA?  Obviously the performance of I/o would be take a hit but I rather he would perform badly only totally cut off IO.

Maybe that's not possible even remotley, but I look forward to comments.  Thank you!

While I've seen this work his * explicitly * not supported by EMC.
