So I was just looking at This Link and thought it would be pretty cool if I made a datapack or mod that implements something like this.

You would start out with a map with an X at a certain location, like the woodland mansion and buried treasure maps. You would have to travel there and once you got there the mod/datapack would give you a challenge. Completing it would give you a reward and the next map. with the power of lore, you could get to the end portal and defeat the dragon.

Is there any way to create the map with a random destination? maybe the banner thing or something?

Thanks in advance, and let me know if this would be something you'd play.
