Robert, Sorry Dude. I did not mean to make things worse. All I wanted to say is this: It can be done via the ifconfig command.
Now,
# systemctl status network.service
Tells me that network services still depend on:
"ExecStart=/etc/rc.d/init.d/network start"
Good! File: "/etc/sysconfig/network-scripts/ifup-eth"
Says: "39 # bail out, if the MAC does not fit"
Ok, perfect. As you already guessed we need to make this change early on. However, if all else fails, you can always source a custom script here and problem solved.
I know, this is not elegant. But as an SA who sometimes needs to do dirty deeds...
Again, apologies if I am being too simplistic/stupid here.

I need the changes to be permanent to apply across boots. Thus using ifcfg-eth0 rather than ifconfig.

ifconfig claims to support it:
hw class address<snip> Also, don't forget /etc/udev/rules.d/70-persistant-net.rules
I can't forget what I don't know. please point me to description of these rules?
