This is similar to a method which oppressive governments use to monitor
their users. Not something that Tor should be involved in.

.onion sites already are secure. I think what you are looking for is a
way to to signal to the user that HTTPS is not required for .onion
sites. I'd lean towards just using HTTPS because that means there is no
further education to be performed. Let's Encrypt could help here.
