I know you're not doing adventure maps anymore, but I've got a very nice idea, and since A Link to Terraria is the best Adventure Map I've ever played, I think I should share it with you, just in case you'll start working on it again, someday
Instead of finding hardmode gear and fighting the Golem, after the WoF fight, you see (actually, read) Ganondorf escaping through a hole in a wall
You follow him there, but you find yourself in a pitch black corridor
You keep walking until you hear a click
After a second, the room lights up with glorious light, and you see a series of golden (painted) statues spelling out a Tinyurl link
If you go to that link, it downloads another map
You open the map, and you find yourself in the same room, this time dark again
Little do you know that you've entered the reign or Lorule (of course in Hardmode), where you'll find yourself in an epic new adventure, much like in ALttP and ALBW
Oh, also, Texture Packs are now easier to make, so you could also make that old Texture Pack shine again
Just suggestions though, don't want to put any hard work on your shoulders against your will!
