I'm dubious. If someone asked me to run such a thing and offered to pay for it, I'd turn them down: It's too easy to be compromised (via hackers, including the state funded kind) or ordered (e.g. via an administrative subpoena, NSL, or plain court order) and fail to deliver on the expected privacy. This false sense of security might even get people killed, when they think their activities are private when they really aren't. You might get a strong selection effect for parties who are less principled, thoughtful, knowledgeable, or even outright less honest. Why should someone trust them more than cloudflare (who is already seeing a substantial portion of user traffic, because if you don't use them-- you get DDOS attacks and then mysteriously cloudflare sales contacting you). The situation with Let's Encrypt is different-- the SSL CA process is already fairly insecure and bogus certs are already easily issued to any party that can MITM traffic to the target server. Even ignoring that ... Any one rogue CA which is trusted by browsers is enough. So there is little to no incentive to compromise Let's Encrypt.
