No, it's not possible after the instance has already been created. Why do you need it as eth0? A requirement of some software that we're using (quite draconian, but a requirement nonetheless). I've modified the packer source and got it to work by adding my own 'network_interface' option, but 'there be dragons' since you can no longer define a subnet and security group and there could be other complications. I would try to submit a PR, but I think that this is such an edge case that it's most likely not worth the maintenance burden for the few people who would need it. I think my best option is to pursue a custom builder plugin.
