Using Orchastrator & Netapp WFA to create Flexclone Test labs?

Being fairly new to the world of VMware and Netapp, I've been looking for a managed solution that will utilize my existing infrastructure to produce a quick/temporary "test lab" that we can use as part of a continuous integration process.

The Situation:

Using mounted NFS exports on a Netapp filer (FAS2240), we have a few ESXi 5.5 hosts (managed by vCenter) that are running linux-based webservers and jobservers vm guests, each that NFS mount folders from another linux fileserver guest

Prior to a web software release, we need to run several scripted tests which *should* be done in an exact replica of our production environment. We used to have dedicated servers for this, but the production systems suffer changes all the time for various reasons and keeping another set of dedicated servers consistent has proven difficult at best. Frankly, we need a solution that's much more flexible and that utilizes the resources at hand. I have heard there are ways of quickly producing such a test lab (for upgrades or software testing), mostly 3rd party licensed software. We can not invest anymore into this area, but we already have licenses for Netapp's FlexClone which quickly provides a temporary volume copy of the 2 production volumes. It's just a matter of registering the new volumes on the ESX hosts, starting the guests inside the cloned volumes, and adjusting the IP addresses (and maybe mac address info) on those guests.

However without the experience I can't tell if I'm heading down the right path here or will I find out after several days/weeks of research, installations, configuration and testing, that this was not what I needed.

The Questions:

Can I use orchestrator (perhaps combined with Netapp's workflow automation) to perform these steps:

create a flexclone of a production volume containing 1 webserver and 1 job server vm
create a flexclone of a production volume containing 1 fileserver vm
register/mount the new volumes with 1 or even 3 ESXi 5.5 hosts (or perhaps the vcenter server?)
add each guest vm on the cloned volumes to the vcenter/esx inventory
make necessary udev adjustments for the new MAC address each of these guests will have (or I can use a vlan?)
(I believe this is only an issue with Linux-based guests; since the mac address changes when the vm is cloned)
edit the IP addresses of each of the vm so they don't conflict with existing network (use some kind of script here?)
send an email to our development team stating the webservers IP address for testing (i know this can happen; just added in the spirit of completion)

If this is possible -- can anyone provide a high-level guideline on what I will need to focus on in terms of software packages, plugins, or am I on the right path and just need to create the necessary workflows and vSphereCLI scripts?

The Environment:

3x ESXi 5.5 - mounting nfs shares from netapp filers running about 20 guests

2x FAS2240 - hosting the primary production volumes

1x FAS2220 - secondary for a DR SnapMirror

1x FAS2200 - tertiary for SnapVault

Note - FAS22xx running OnTap 8.1.3P2 in 7-Mode

1x VMware Virtual Center 5.5 server standard (on separate stand-alone esxi 5.5)

- vSphere Virtual Storage Console 4.2 plugin

- vCenter Orchestrator 5.5.0

1x NetApp Server (a vm guest on same esx as vcenter)

- OnCommand Unified Manager Core 1.3

- Management Console 3.3
