I can only see them adding a little Raidou side story in Tokyo, some optional demons from the new Raidou remaster, and maybe bug fixes. Also, please do never talk about dungeons in context with SMTVV. It just did not work, and they were the worst part of the whole game.
Some post game content like 4A would be incredible though. But the VR trainers are SMTVV's answer to that.
