Could 'Superbad' Dip Into the 'Pineapple Express'?

Cross-overs, an old television standard, have been slowly making their way through the world of cinema. But forget the geek crossovers that popped up this summer because there might be a more comedic twist on the way. While talking with MTV, James Franco says there has been discussion about a crossover sequel for Superbad and The Pineapple Express. But it wouldn't be a normal intermingling of characters.

Franco noted that Seth Rogen and Evan Goldberg weren't very interested in the idea of a Superbad sequel, "And so, an answer to that was to do a Superbad/Pineapple Express crossover, an unprecedented crossover movie with two directors, Greg Motolla and David Gordon Green, each directing half of the movie and somehow these characters get together, which doesn't make sense at all, but could work."

I could see a scenario where Seth gets too into Saul's weed after feeling shunned at the burgeoning friendship between McLovin and Evan, gets into trouble, and Evan has to save him ... maybe with help from the flying-through-the-air Dale and information from Saul. What I don't see is how it would work to do a half-and-half movie.

But what do you think? Should all the kids meet? If so, how should it be done?
