Other commenters have already covered the political/financial difficulties of this, so I won't mention those.

However, the journey of CertSimple may be marginally relevant to what you're proposing.

They were a small CA focusing entirely on the easy issuance of Extended Validation certs.

Disregarding the fact that EV never actually had any proven value (except for some code signing use cases), they did have a nice little business.

As far as I know it was a one-person company at first, and they were able to piggyback off the infrastructure of an existing CA. I can't remember whether it was an intermediate cert or simply reselling.

I was going to link to them but they seem to have shut down or been absorbed into another company.
