Yep, maybe using ssl offloading devices like (BigIP) that receives tls1.2 and tlsv1.2 and then re-encrypts traffic with tls1.0 might be "cheapest" solution.
Perhaps re-evaluate the need to have TLS 1.1 and 1.2 right now. The only attack against 1.0 that I'm aware of is BEAST and that has been largely mitigated by browser-side fixes to the point where TLS 1.0 is now considered to be safe. No doubt there will in time be other attacks that necessitate an upgrade, but for now I would just stick with the version of openssl and apache that comes with CentOS 5 and focus on moving to CentOS 6 or 7 as a medium (not long) term goal. At the end of the day I think it's better to just go this route than have to deal with the hacky solutions for getting 1.1 and 1.2 out of CentOS 5.
