I'm not sure what you are trying to achieve here - PTR records and A records are completely separate entities living under different domains. Both of them should be maintained separately (there are probably tons of tools to keep them in sync if you like, but from DNS' perspective there is no relation between them).
If you want to "prevent reverse lookup" then you should tell the client not to do this.
