This was an attempt in that direction, which doesn't have the desired effect:

{
    packageOverrides = pkgs:
     let
       emacs = pkgs.emacs24-nox;
     in
     rec
     {
       djr = pkgs.buildEnv {
           name = "djr";
           paths = with pkgs; [emacs mu];
       };
     };
}

nix-env --dry-run -i djr
