Well for the guys who came back, it helps that they wern't literally vaporized into a pile of ash. Because that might be an issue.

And, I've heard of cloning through DNA, but... I don't think that would quite work with blood...

Theoretically, Epsilon could form together some kind of memory amalgamation to replicate York, but... at that point, that's just getting desperate. If Carolina wanted York back so badly that she asked Epsilon to make a York out of old memories that she could pretend to be the real York... she'd have to be going pretty natshit crazy, it would lose a lot of the character development she's had, and would generally just be really fucking creepy if I do say so myself.
