I don't think it's possible. OpenSSL says, in the NOTES section of
The TLS standard (or SSLv3) allows the integration of
compression methods into the communication. The TLS RFC does
however not specify compression methods or their corresponding
identifiers, so there is currently no compatible way to
integrate compression with unknown peers. It is therefore
currently not recommended to integrate compression into
applications. Applications for non-public use may agree on
certain compression methods. Using different compression methods
with the same identifier will lead to connection failure.
