To give my answer to the original question, yes it is possible in the context of the subsequent story of Tamriel. No one knows for sure, the only refernce I've come across to her/him travelling to Akavir is in an overheard conversation during the Oblivion crisis. Said conversation has as much validity as reading a post on Twitter.

I once read a science fiction book that offered the concept of  uniiverse that split into different lines of reality everytime a major decision was made, so new universes were created all the time. If one applies that dubious logic to the virtual world of Nirn, then one could argue a new virtual reality was created every time someone played the game, so any fate could have awaited the Neraverine and anyone he/she came into contact with. So one can imagine whatever outcome one chooses and it will be just as valid as anyone elses. Whether that means Vivec and Helseth were killed by the Nerevarine, or they lived happily everafter; it's your game, your (virtual) reality, you choose.
