They do have connections; they are the archenemies of Marvel and DC's best known superheroes, both came to be after coming in contact with dangerous chemicals, and use both chemical and psychological warfare on their enemies.

I would find it interesting on who would outwit or overpower their opponent first, considering Joker's high pain tolerance and manipulation versus Goblin's high-tech weapons and persistence.
