As far as I am aware, you cannot change a pod after it has been started. A pod *can* talk to the Kubernetes API to start more pods, and I believe you can use node affinity https://kubernetes.io/docs/concepts/configuration/assign-pod-node/ to make sure that a new pod gets scheduled where you need it. Depending on your use case, putting both in the host network namespace may or may not be necessary.
