Personally, I think I would love to see a nightgaunt or a Byakhee, I think we've seen Watley's twin Brother (Shouldn't he be invisable? LOL) or was that a weird Shoggoth?

Dr. West will likely make an appearance soon.

But what I would most love to see is a refrance to Chuck Ward. I loved the ending to that story... Doc goes to the Imposter says a couple words he memorized and poof, problem solved. Poor guy doing what he had to to spare the family...
