Even if you could I would highly recommend against doing that, given that this would grant you access to every https connection that isn't hpkp secured.

I actually have all webservices in my home network secured by https, all you need to do is click a cheap vps, install nginx and tinc, and then proxy /.well-known/acme-challenge/ to your internal servers. Either setup domain or ip hijacking so the public IP is routed inside your lan. Done.

If I can do this for me and my cat in my spare time, you can do this for your university.
