Yeah, here's some things that would be nice to see:
Valeria interacting with the Champions. Nadia, Amadeus, and Riri would all want to compare notes. Val thinks she's smarter than everyone. But she won't know Nadia and Riri even exist. She should meet Moon Girl too, for the same reason.
Reed interacting with Ms Marvel. Their powers are similar. I bet Reed would enjoy analysing her! Maybe they could teach each other some new tricks.
Franklin interacting with the Power Pack, who need an update about where Alex is.
Sue interacting with ANYONE.
