I think that's the hardest part, knowing whom to actually contact. What i understand from reading about it, is that it's unclear who owned the rights in the end after all the legal back and forth.
And i'd be somewhat pessimistic, if it's a big player. They probably won't give out licenses for a reasonable price, even if the game is technically abandoned.
Though i'm all for it.

Edit: i remembered that some contracts for cases like this have a non-transfer clause in them though; that would mean after a studio closes the rights are no longer with them. Maybe that's something to dig deeper about.
