Glados could be in there, she'd just have to hang from the ceiling. Like always. Or you could go P2 and have Carolyn be there in her stead. There's pics of her up on youtube and in the game if you need a reference.
In fact, Carolyn would be suited for this picture, since . . . well, if you don't know, play the game. If you do, don't spoil it.
