Personally I think that the Totsuka blade could pierce the Yata Mirror if only because of what happened between the Third Raikage and Naruto. The Invincible Spear proved stronger than the Ultimate Shield so it would make sense that the Totsuka blade would be stronger than the Yata mirror. But even if they were exactly equal in strength it would hardly matter because unless those two weapons manifested in another Susano, which is only really possible with Shin or Sarada, they both died with Itachi. Still if Shin did manifest the Susano it would likely have very different weapons than any other Susano. As for Sarada her uncle was Itachi so it's possible that she could manifest the Totsuka blade and Yata Mirror but that would be almost miraculously unlikely.
