I'd like this to happen. I get that in the early days v1 was the equivalent of normal, with v2 essentially the veteran level, but the conceptual aspect of story continuation in v2 made it interesting. Currently normal is only used as a casual experience or training run. The original conceit of stand alone, multi part stories would make repeating the content more attractive in my view. This also adds a much needed intermediate tier of difficulty. Maybe even a v3 for older content wouldn't go amiss either.
Lock part+ behind completion of part- to provide progression.
Edit
There are plenty of dungeons with scenic doors and dead ends that could easily be extended to add new areas instead of dropping entirely new dungeon locations. Surely this would be cost effective development and provide incentive to run older dungeons - - familiarity would yield better dungeon experience too

just thinking out loud.
