I see why the video reminded you of the CQ2 sewers, it looks really cool. Honestly the more Chex Quest stuff the better I'd say. This reminds me of a topic we had about role playing a long time ago. It's not entirely the same of course, but back in the day I'm sure the fandom would have eaten this up.
Given the current state of the forum, I doubt we could get many people to try a Chex Quest D&D event.
