So I came up with this. What if Irina somehow managed to rebuild Dr.Marcovic's doubling machine and doubled her as someone else and let someone take her place. So jack thought he killed Irina but actually she's alive. This way JJ could bring back Irina with another actor. I know it wouldn't be the same but who knows? Maybe the new actor would be great.
So what do you think?
