I doubt it. Too late into the story, I think.
As much as I like the old characters, I'm much more interested in seeing new ones develop their own distinct and lovable personalities. DeSinge, Morgan, Van Winslow come to mind, as to the judge, McGillicutty, Anemone, Hemlock (how he takes care of his cat, it made me coo). These are all examples of characters I would like to see more of.
(Or would have, in two cases.) I like how they turned out, mind, and I'm happy Telltale are finally figuring out how to make memorable supporting characters with so little development time, and that's why I'm so looking forward to whatever they do next.

Remember: you loved the vegeterian cannibals because they were original.
