Is there even a chance that Alec could still be alive?

So, of all the cinematic deaths we see a body to confirm it's death. With Alec (both times) they decide to fade to black. Where at least the 2nd time they could have shown the body. I suppose in both cases fading to black makes sense as Ryder is going into a unconscious state, while Alec is well dying. However, BioWare as brought people back from the dead, before: Leliana and Shepard. They've also used misdirection in promotional material before such as Blackwall, Solas and Ellen Ryder saying she "died"-even in the codex it says she died on Earth at first. How could this be possible? Well, we know that its possible to bring someone back from the dead with Project Lazarus. This could be possible with the Benefactor it seems that the Benefactor as connections all over the place. Consider that the A.I. has blueprints to the Normandy SR2 that was constructed in secret by Cerberus. How did A.I. even get those plans? Benefactor? So, it's possible he/she/it also managed to bring over Project Lazarus.
