nixos-option for NixOps deployed machine?

There is a command nixos-option which examines given system's option value. Under the hood it does something like:

$ nix-instantiate --eval -E '
  let nixos = import <nixpkgs/nixos> { };
      opt = nixos.config.networking.firewall.allowedTCPPorts;
  in builtins.deepSeq opt opt
  '

$-> [ 1194 22 8081 80 443 4949 ]

But that doesn't work for NixOps deployed machines (configuration isn't available there). Is there a way to get option value from NixOps deploment config, on deployer machine?
