Yes.

One way could be to configure a template machine that you clone from.
This machine will probably use with dhcp, and a firstboot script that is
run only on the first boot for each cloned machine. This script could
regenerate the ssh key for the ssh server, and poll additional scripts
from another server that sets the hostname and a static IP address. (I
wrote an instance manager for AWS a few years ago that could spin up any
number of instances based on some rules, and with a combination of
first-boot scripts and scripts generated for each instance, everything
was 100% automated).
