I seriously doubt Chrome or Firefox would ever be coerced into trusting a cert like that. If they did then you would see a very rapid shift away from those browsers to one or more of the open source alternatives.
And any CA that issued such a cert that allowed for wholesale MITM access like that would be blacklisted by all the browsers very quickly as well. That would put the CA out of business very quickly.
HSTS just enforces HTTPS over HTTP.
