If you wish to completely override the src, use:

my_mathematica = mathematica.override {

  source = pkgs.requireFile {

    name = "Mathematica_XX.X.X_BNDL_LINUX.sh";

    # Get this hash via a command similar to this:

    # nix-store --query --hash \

    # $(nix store add-path Mathematica_XX.X.X_BNDL_LINUX.sh --name 'Mathematica_XX.X.X_BNDL_LINUX.sh')

    sha256 = "0000000000000000000000000000000000000000000000000000";

    message = ''

      Your override for Mathematica includes a different src for the installer,

      and it is missing.
