I think we should go ahead with the rouge Adepta sororitas, at least one order/chapter that was formed by the ones who were captured by Vulkan when the Ordo Vulcanus sent them to kill him.
I mean, we already have a whole Rouge imperial Guard army under his command, and since he accepts and is trying to convince everyone into seeing the "truth". It wouldn't be far from the realm of possibility that some Battle sisters would join him, since there actually chaos Adepta sororitas in cannon...it would be less of stretch with them joining vulkans.
I am guessing they wouldn't be called sisters of battle though, at least the specific order that defects they would get a name change like the Vostroyans.
