Ruby interacting with Maka Albarn could be nice. It would be even more interesting if Qrow and Maka's dad are also interacting with each other.

Speaking of meta, Agent Carolina talking with Pyrrha could be entertaining.

About the only original (don't seeing the combo before) one I came up with would be seeing Penny interact with numerous other sentient AI/robot characters. EDI, Legion, and Chamber are the first three that come to mind.

This is less about team ups, though that is not mutually exclusive, and more about the character interaction.
