You can't be the "Let's Encrypt of" anything if it's self-hosted. The entire point of Let's Encrypt is that there is a centralized reputable entity of note signing everyone's keys. Without that, it's entirely worthless. It's no better than a self-signed SSL cert or putting your own PGP key on a document manually. There's no point in a layer of abstraction atop that.
