1. dasync_aes128_cbc_cipher (search for this in https://github.com/openssl/openssl/blob/master/engines/e_dasync.c) || replace it with your symmetric cipher, and do the same for RSA.
2. setup a server and client and hard-code the symmetric & asymmetric ciphers to your ciphers
3. your idea is simply not going to work. Like Tobias said, you have to add them manually. I suggest you simply not use OpenSSL or any TLS library, unless you have a lot of clout in the International Communication Union.
You can take Mega's approach and use _javascript_ since every browser under the sun has it (as an additional layer over TLS).

As far as I know, you will need to have an OID assigned for each
algorithm for x509 certificates. You can add those to OpenSSL manually,
but you won't be able to communicate with any other software that does
not implement them. (And as Rich said, there is little reason for people
to trust and use non-standard algorithms.)
