Comment (by cypherpunks):

 >  It looks to me like that would work
 I think it must to work. The only thing is about updating openssl code in
 future? What if new methods for new tls version will use something
 different than ssl3_get_cipher_by_char. With SSLv23_method we at least
 sure it will support any new tls version while openssl exist.
