Just make sure you have a good DRS of the publisher so that if anything happens all you have to do is reinstall the VM and restore the backup. Unless you’ve multi-purposed the Pub (with TFTP, etc.) then it’s just the configuration databases that gets pushed realtime to the subs so if it fails operations will continue.

Really you should have no dependence on the publisher besides configuration updates so it shouldn't be anything that affects operation. I would be concerned that the subscribers would have a more updated version of the database than the cold-standby publisher.

Waiting your feedback.
