Are you really sure 6.5? AFAIK 6.5 is no longer supported.

At least corosync 2.x should work just fine on RHEL 6 and there is no 
hard dependency on systemd.

Take following comment as just my 0.02$. Honestly I would go with what 
distribution provides. RHEL 6 is still supported and what is there is 
tested by QE/other customers in production. If you decide to go with 
newer versions on top of old distro you are on your own and you may face 
weird bugs which nobody will really care about much.
