Isn't Arcanna Jones the customer that Darcy serves in the last pages (after Wanda and Agatha part ways)? She is called "Jonesy" by Darcy, and the fishnets and the outfit's color combination are the same as Arcanna's costume.

Nice catch, but I'm unsure of which Earth, or is this the 616 version?

Good question, hopefully she will reappear in a way that removes the doubt. She could be the 616 version of Arcanna since there are characters from Earth-712 who have a counterpart on Earth-616 (Kyle Richmond above all).
In theory there should be no survivors from Earth-712, from what was narrated in Squadron Supreme 9. But she might have survived, as Power Princess did.
Which could be confirmed in Secret Warps: Arachknight Annual since the Arcanna Fenzi named in that story is supposed to be her "fusion" with Lenore Fenzi from the New Universe.
