Uh, I was also thinking that it could be a possibility.
But honestly, given the attitude of Mrs Cringe, I would think she would be more on the line of bsdm stuff (spanking, flogging and stuff like that falls in the category, I think), using and abusing Myriam with toys (maybe, since there was a reference to toys, and in part coudl fall under the bsdm as well), and the "graphical violence" (all mentioned in the tags), than trying to have sex with Myriam.
The fact she uses religion could open to the possibility that the priest also get involved (or on the other hand, that Myriam goes to be helped with her "possession" or anyway to atone for her sins, and the priest does stuff with the help of Mrs Cringe). But the "priest events" path depended on the choices made by the player, so linking the two too much would risk closing a possibility, making the extra activities with the presence Mrs Cringe linked to have opened the priest route.
At the same time, I don't remember if Zorlun has already excluded the possibility of Mrs Cringe being anything more than a nuisance, but I think so - if that is the case, it would exclude anything like what we are talking about.
Or she may end up playing a role with the priest (given the religious element), but only being verbally aggressive, like a tool to modify a bit stats and inclinations, a bit like she has done till now.
