I’ll say the Jetsons, since I like the Jetsons, and I’d like to see how they’d interact with Cyborg.

Wacky Races, with the Titans joining the race.
Or bring back the Super Friends. The contrast could lead into some pretty comedic stuff.

I would think they would meet all of the characters from the animated Scooby-Doo movie, SCOOB!, after the events from that movie, where the Titans and their Little Buddies, join the Mystery Inc. gang (again after the events and their encounters from the Titans from that funny episode, Cartoon Feud in Teen Titans Go!) and the Falcon Fury (now with Captain Caveman, Atom Ant, Jabberjaw, and Grape Ape during the credits), to fight Dick Dastardly, and Muttley joining forces with Slade and Trigon to summon a creature greater than Cerberus.

And for this outrageous TTG! episode, it’s when Robin receives a notification from an top agency which represent Super Heroes, that they got for him a “matching” sidekick. And Robin was so excited, that he told the other Titans the great news. But it was until Robin gets a shock, when his new sidekick (enters inside the Titans Tower) is that little duck Yakky Doodle.
