Is there interest in patient gaming for WoW?

I've been thinking about this for a while. I'm not a big raiding fan or pushing cutting edge content. And my real life has taken most of my planned time. But I like to see and experience the story. I was wondering if there would be enough interest among players to make a guild or community around doing older content? I was thinking probably n-1 or n-2 expansions.

Maybe for "hard" stuff we could do time walker raids lol.
