Maybe the crew has to team up with the Avengers to keep the stone from falling into the wrong hands. Another plot could involve a transporter accident that sends a Star Trek character into the Marvel universe and they have to find a way back while getting involved in a local Marvel - style conflict.
Well, perhaps the Borg from Star Trek start assimilating technology from the Marvel universe. This would draw the attention of Iron Man, who would then seek the help of the Starfleet engineers to combat the Borg.

Or perhaps a Transformer gets beamed onto the Enterprise and has to adapt to life among the crew while they figure out how to send it back to its own world.
Maybe there's a race in the Stargate universe that has developed a technology similar to the Borg in Star Trek. The Starfleet and Stargate teams come together to study this new threat.

The Jedi could learn about strict emotional control from the Vulcans, while the Vulcans might be intrigued by the concept of the Force.
