I'm sure it would feature those, but they've got a big long list of baddies. I'd think a big Villains Land expansion wouldn't focus on just a few, it would be the place you could reasonably expect to find many of them - at least the ones of a certain ilk.
I don't think Hans would set up shop in Villains Land, for example, or Dawn Bellweather or Alma Madrigal, but the older-school, conniving, mustache twirling, good-to-be-bad ones probably would. The ones who could be found lurking in the shadows up to no good, stealing away to a secret meeting in a spooky tavern or hiding in a secret lair in Bald Mountain.
Dr. Facilier falls more into that sort of category with Maleficent, Captain Hook, Jafar, Cruella, The Wicked Queen, Hades, The Queen of Hearts, and Chernabog than he falls in line with, like, the contemporary twist-villains Disney's been doing lately. Those don't seem wicked enough to fit the bill. I would think Villains Land would play host to a smattering of those evil guys in one way or another, not just be home to a small handful.
