Given how Mercy describes the dwarf's penis, I'd say she's playing Sansa. Glad to see the Stark sisters finding accord, after all.
Haha that was one of my first thoughts as well, how Arya thought it was done all wrong, all crooked with a bulbous purple head.
It was made to flop out, for the rape. What a hideous thing, Mercy thought as she knelt before the dwarf to fix him. The cock was a foot long and as thick as her arm, big enough to be seen from the highest balcony. The dyer had done a poor job with the leather, though; the thing was a mottled pink and white, with a bulbous head the color of a plum.
Yet what Sansa described in ASOS Sansa III:
Even his manhood was ugly, thick and veined, with a bulbous purple head.
After which point Sansa goes on to lament to the Gods how they have punished her for inflicting such a husband on her.
Further, Bobono complains to Arya:
With that, he grabbed at her chest, fumbling for a nipple. “You have no titties. How can I rape a girl with no titties?”
Which incidentally was one of the main reasons Tyrion did not go ahead and consummate his marriage with an unwilling Sansa: he did not want to become a rapist of a girl hardly more than a child.
As for whether Mercy played Sansa or Shae, the main character is probably meant to be Sansa, a maiden raped by her bitter and angered Lannister dwarf husband, but most likely some elements of the Shae story has been melded into it since well, rumours. There's also the fact that Sansa disappeared and was never found again, which for most people means "death" so I imagine for most people they would assume Sansa was dead, and that Tyrion probably killed her.
Regarding playing Sansa in the shapeless brown dress, that dress is Mercy's dress. It's specifically mentioned that she could nick something from the wardrobe, but that Izembaro woud know. All the other actors are in costumes, so it's most likely Mercy will be too. And she was not to come on until Act 2 either which gives her some time to prepare her oufit.
It really reminds you of Varys, the shaved head and the mummery. Only it seems to me, Arya is a better and more skilled assassin than Varys. It says even Izembaro agreed she was "graceful" even if she still cannot sew. Arya also threatens Bobono with making him a eunuch, so the Varys references are there.
As for Lady Stork, she seems to be playing Cersei in cloth of gold, and there's supposed to be a wedding scene. Sansa/Tyrion's or Joffrey's?
