It will work.
Exporting iSCSI would be better.
Not using harware RAID on FreeNAS, and using software RAID Z, Z2 or Z3 
would be even better.
Why do you need RAID5 on the Proxmox server if the VMs are stored on a 
separate system?  If it is your only Proxmox system (i.e. not a cluster) 
then RAID is useful, but otherwise not really necessary.

Unless you're running OpenVZ containers, in which case forget everything 
I've said here, except that LVM-over-iSCSI might still be better/faster 
than NFS... not 100% certain, I don't use containers.

If the storage server is dedicated to Proxmox, then iSCSI allocation 
isn't an issue - just allocate 100% of your disk space to the iSCSI
