I have to disagree, the author's already shown that Priscilla does actually exist and considering she acts the same way at home (Sunlight on the Water) it's not really an act. None of your evidence except for the last one have anything to do with your theory, and even then it's just speculation. I'm still leaning toward Subaru having it based on his Returns by Death being described as one and Shaula's words

What my theory lacks is the Arc 5 part. Why would Aldebaran and Pandora (Priscilla) fight Capella and Capture Sirius? I'm still really positive on my theory, Aldebaran knows too much about the Archbishops

I might be forgetting something but where does it show that Al knows too much about the Archbishops? As far as I know he was just acquaintances with one. As for Sirius, they'd fight her because she's an enemy of Lugnica

There's also the fact that Priscilla predicted where Subaru would go in arc 3 and that he would want to enter the castle (she even told Al what Subaru would say), you can check the manga. She might have a gospel

Gospels show the holder's future in little detail, so I doubt it'd tell her to pick up Subaru. She probably figured he would through their exchange the previous day
