Everything you've said is pretty interesting, Will-O-Wisp, but I have one idea to throw at you, with regards to whether or not Yhwach activated the Vollstandig remotely or not. It's possible that he did, given that he has spoken about the existing Quincy being of his bloodline and given his credibly immense power. But one other thing. Check the panel where Bambietta's about to go Vollstandig and Shinji's like "lolwut?". There's some kind of shard extending from Bambietta's chest, and I don't recall such a thing occurring when Quilge activated his Vollstandig. This would suggest to me that Yhwach has himself activated his Sternritters' Vollstandig, as does the fact that Cang Du was, near as I can tell, immobilised by the ice prison. Unless they can activate it via thought, I'd say Yhwach did it.
