I've investigated the potential for developing an engine to support this as it would mean I don't need to touch the core openSSL code. However, I've two blind spots which I can't find any answers to...

OBJ_create() is the easiest way. You pass it the oid, short name and long name
and get back a NID.

No. There is no mechanism to dynamically add ciphersuites to OpenSSL at
present.
