So, an idea inspired by some discussion in one of the quest threads:
An alt trigger Glaistig. Instead of collecting dead capes and bringing them forth as shades, she resurrects them wholesale. They're still dependent on her to be in the real world though- she can only support so many at a time, and the rest of the time they're stuck in a pocket dimension. There's also probably some geas to keep them from harming her. While they're in the pocket dimension, they can walk around, talk with one another, even fight, but they can't die.
Basically, Ciara ends up being Valkyrie from the get go. She's still kind of crazy (or at least seems that way) and is going around collecting capes that have "died honorably in combat", but since she isn't actively killing capes, the PRT is ok with that. She can support three of her claimed indefinitely, but if she spends time without any of them in the real world for a while, she can build up a "charge" to allow her to surge more.
Not sure if she would be participating in Endbringer fights, or if she's saving everything for "Ragnarok".
Plotwise, obvious solution is to have Taylor die and get collected, but having her grab Aegis and Gallant might be equally interesting.
