I am personally keep thinking about The Halls of Arden Vul, seems like an awesome thing to run. But I have to admit it's a bit intimidating due to size and complexity and I can't, for the life of me, decide what system to run it with. But it's been there brewing at the back of my head for almost two years now..
I would think either of those would work well. I know B/X stuff is generally fairly compatible with AD&D, and afaik AD&D 2e isn't that different. And Hyperborea seems very cool.
