I have a branch where I've worked on such a thing. It's still work in progress, and I haven't looked at it for a while due to other things having priority, but I intend to get back to it. It won't be a straight port, as there are bits in there that are... ugly, especially the ad-hoc controls to fetch stuff that the ENGINE API doesn't have specific support for (certs and list of certs and whatever other stuff I forget). I'm replacing with support for the OSSL_STORE API, so those things can be fetched in a better supported manner.
