That seems like a terrible idea.
Why not just assign multiple IPs to eth0 instead? Or create a virtual interface?
In case if you e.g. have eth0 and eth1 and neither is guaranteed to be up. It's more of a router setup, though (Cisco routers are well-known to use the loopback interface like this).
Ahh, interesting.
