Yes, you can create an Instance-store AMI out of an EBS based instance.

1. Install ec2-ami-tools in the instance
2. Upload your x509 certificates to the instance
3. Use ec2-bundle-vol and ec2-upload-bundle commands NOTE: You need your account ID, Access Key and Secret Key to run these commands
4. Register the image specifying the bucket/manifest name where you have uploaded the image files.
