Since Amara could probably lock up Chuck by herself, especially in his weakened state, bringing her back would create too many storyline problems.

Under the current Canon, Chuck can only be imprisoned, not killed, if the universe is going to survive and everyone knows it. However, being confined for eternity might be Chuck's greatest fear, as it was Amara's, so maybe for him that would be a fate worse than death. Or, it could be that no one worships him or prays to him any more and that makes him weaker (think Zeus). Apparently, according to Castiel's interpretation of the Demon Tablet Michael knows for sure but he's not telling at this point. So, I currently don't see much of a role for Death, either old or new, because Chuck cannot be killed and he and Death and everyone else knows that, at least under the current Doctrine.
