I'd love to see a Kolchak: The Night Stalker/Early Edition/Special Unit 2 crossover.
Each show was set in Chicago.
Kolchak wrote for INS, the Independent News Service, usually about strange creatures or events.
Gary Hobson from Early Edition would receive tomorrows paper today, and set out to help someone in the paper. Reading a Kolchak story bought by the paper from INS isn't out of the question.
Special Unit 2 was a police division that had jurisdiction over supernatural and mythological creatures in Chicago, referred to as 'links.'
I know there's at least one story in there somewhere.
