That's a great question. And much like 'how many licks does it take to get to the tootsie roll center of a tootsie roll pop' the world may never know.

My thoughts on the matter though are no, he might not have had the power to save Cora without having killed Boyd. Peter basically called it a Hail Mary that might work or just kill him, and then leave Cora in a minutely better position than she was, causing her to die a bit slower.

Personally, knowing she was leaving the show, they should've just let it not save her. Burn out his alpha power if necessary, but not work like they thought it would or something.
