In NixOS, is there a way to use Rofi instead of Dmenu when invoking Passmenu?

I'm using the pass package for password management. The passmenu command that comes with it uses dmenu, but I'd like for it to use Rofi instead. I saw [on the Arch wiki](https://wiki.archlinux.org/index.php/Rofi#Rofi_as_dmenu_replacement) that it's possible to use rofi as a drop-in dmenu replacement, but the path structures of NixOS are so complex that I'm having a hard time figuring this out. Should I create a new package for it? Or is there a way to update [the original pass package](https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/security/pass/default.nix) so that it uses rofi instead?
