This sounds very interesting! I was hoping to get something small and
suitable as a starting point with internal registrar support and your
description seems to match that quite well.

Yes, very much so. You can publish the package on your web server or I
can alternatively host it at http://w1.fi/contrib/ with other WPS

Taken into account that this topic comes up every now and then, it might
be useful to get the patch available somewhere. OpenSSL is not exactly
the easiest piece of software to make smaller, but it is still quite
widely used even in many embedded systems, so options for reducing code
size are quite useful.
I will use more of my time on trying to make sure the integrated
crypto/TLS code option in 0.6.x branch gets more mature and can handle
all the needed functionality, including WPS, to provide an option of
getting the total binary size down quite a bit more, but anyway, I can
host a patch for OpenSSL and you could also ask whether OpenSSL
maintainers would be interested in it.
