Better rested, I now re-read it and I'm having my doubts.

Deliora seemed pretty much the same kind of raging beast both before and after righting Ur, so I doubt that part of your theory will be in the actual story.

It'd also make things needlessly complicated. Silver could have just been a random mage who knew both Take-Over and Ice Magic, who wasn't related to Ur. He tried to take over Deliora, but ended up merged with it instead. Either his Ice Magic was Devil Slayer Magic from the start, or it is the result of his Ice Magic merging with Deliora's Demonic Curse, or maybe even something that Mard taught him for one reason or the other.
