Gothic Sequel's story can still be reused

If you don't know what I'm talking about, it was a proto-Gothic 2 but instead of a full blown second game it'd be more like a standalone expansion.

What I've thought of today was that maybe the storyline of the Sleeper trying to return and a demon plague spreading through the Mine Valley could be reused for a game set like 20 or more years after the original, with a new cast of characters.
