how does that work with https?

Just install nginx that answers to http and https and return empty gif or 204.

Would that fail because your sever can't provide the right cert? You'd probably have to install a custom root certificate on your machines that you https ad blocker could use to forge certs.

Yes, custom cert has to be used, otherwise browsing could be very annoying.
