I ran through Wilderland, after starting with The Marsh Bell. I went through it, organized it into Fronts, and made a campaign out of it rather than unlinked scenarios.
There’s a dark force in one that I turned into a big bad prelude to the Darkening style. I turned the Mewlips into an invasion force that infiltrated the lake and built a lair in the sunken corpse of Smaug, and I dumped the final dragon scenario, and replaced it with an upgraded battle that I relocated from one of the earlier scenarios.
I also dumped the dream elf sequence, and replaced it with their convention scenario.
