More American Horror Story alums trying to return

Seeing that American Horror Story: Coven seems to be the show's most successful season yet, and it's only four episodes in, it would make sense that more actors from previous seasons are trying to return. We first learned that Dylan McDermott expressed some interest in returning for Coven. Now we have word that Connie Britton, who portrayed Vivien Harmon in Murder House (aka, season one), has expressed the same interest. Britton told Rolling Stone, “I’m like, ‘I’ll put that on and jump on a plane and go to New Orleans. Yes, I would do that. As long as we can figure it out with both productions, I’m in. I hope it happens.”
This is to be expected in a way. McDermott appeared on Asylum, but Britton only had one season on AHS. Not to mention Taissa Farmiga who played their daughter, Violet, in Murder House is getting her second shot on Coven.

However, I would expect this to actually happen. Even if Coven is still shooting I don't think they would want to randomly write in new characters just because people wanted cameos. Then again, maybe they would. For the fourth season I wouldn't be surprised to see either McDermott or Britton resurface, though.
As far as Coven goes, we only have a handful of newcomers to AHS as a whole. So far the list of AHS veterans who have appeared on more than one season are:

Jessica Lange (1-3)
Evan Peters (1-3)
Sarah Paulson (1-3)
Frances Conroy (1-3)
Lily Rabe (1-3)
Zachary Quinto (1-2)
Denis O'Hare (1,3)
Taissa Farmiga (1,3)
Jamie Brewer (1,3)
Robin Bartlett (2-3)
Alexandra Breckenridge (1,3)

The Coven newcomers include, but are not limited to:

Emma Roberts (3)
Kathy Bates (3)
Angela Bassett (3)
Gabourey Sidibe (3)
Josh Hamilton (3)


Wait until next season, guys. I'm sure we will see more people returning. Especially if this season has a killer finale.
