True, you could use secedit /export to export the current security settings on a system to a configuration database on Windows 7. However, this only gets things you can configure under the local security policy - it won't get anything under Windows Settings or Administrative Templates in gpedit, so if you want those settings, you have to live with manually copying \Windows\System32\GroupPolicy to redistribute it (and hoping the gPCMachineExtensionNames GUIDs match on all machines), or apply registry settings for those settings instead from a .reg (but this doesn't enforce if changed later, of course, like policy would).
You might be interested in looking into Microsoft's Security Compliance Manager (SCM) instead.
