The reason why I'm skeptical about this is that Weiss not only has plot armor (Pyrrha's more of a side character), but the fact that she still has an arc involving her company. Pyrrha only died after her crisis with the Maiden powers was rendered moot when Cinder stole them and ultimately removed her from the choice that she had to make. Additionally, Pyrrha's overall personality wasn't that noteworthy other than being a talented, kind warrior who was smitten for Jaune, while Weiss has a long way to go, with motivations (albeit ridiculous execution IMO) to boor. Pyrrha was already fully developed until the Maiden Arc.

Additionally, it's plainly obvious that the CRWBY knew of the meaning of a Pyrrhic Victory, so it was plain as day that something bad had to happen to her eventually.
