This actually ended up being a lot easier than I thought it would. Putting notes here for posterity:

Read: http://chrislaskey.com/blog/342/running-multiple-redis-instances-on-the-same-server/

In the post_tasks of the playbook where you install the original instance, re-use the original redis.conf.j2 and set any variables that you want to change.

Important ones are:

port
logfile
config file
pidfile

post_tasks:
    - name: Redis Plutonium data directory
      file: path={{ redis_plutonium_dbdir }} state=directory mode=0751 owner=redis group=redis
    - name: Ensure Redis Plutonium is configured.
      template:
        src: templates/redis.conf.j2
        dest: "{{ redis_plutonium_conf_path }}"
        mode: 644
      vars:
        redis_daemon: "{{ redis_plutonium_daemon }}"
        redis_port: "{{ redis_plutonium_port }}"
        redis_logfile: "{{ redis_plutonium_logfile }}"
        redis_dbdir: "{{ redis_plutonium_dbdir }}"
        redis_save: "{{ redis_plutonium_save }}"
        redis_appendonly: "{{ redis_plutonium_appendonly }}"
        redis_appendfsync: "{{ redis_plutonium_appendfsync }}"
        redis_instance: "-p"
      notify: restart redis
    - name: Ensure Redis Plutonium has startup script
      template:
        src: templates/redis-server-p.sh.j2
        dest: /etc/init.d/redis-server-p
        mode: 751
    - name: Ensure Redis Plutonium is running and enabled on boot.
      service: "name={{ redis_plutonium_daemon }} state=started enabled=yes"
    - name: adjust perms of newrelic file
