I have no idea what would bring this team together. But I feel like it would be a really fun line-up. A lot of them are already paired up - Monica and Adam, Billy and Teddy, Kitty and Illyana - which means you'd get plenty of interesting dynamics in splitting them off with other people. Sera tutoring Illyana and Billy. Adam, Kitty and Bobbi doing science together. Monica training Teddy in leadership. There's a lot of other potential relationships there, too. Maybe Bobbi teaches Teddy to be a better spy. Adam grills Sera about Heven, excited to learn about a world he hasn't heard of. Kitty and Billy bond over their Judaism. Bobbi and Illyana bond over their shared love of snark (and maybe get into some friendly pranking).
On a fun note, Secret War: Siege had a version of Illyana involved with Leah of Hel, who Sera (and Angela) adopted as a daughter. I don't think Sera knows that Illyana is the one Leah's searching for. So that could be used for a little bit of dramatic irony. And, of course, it could always lead to Leah visiting her "mom," and finding Illyana, and then all sorts of drama resulting from that. Preferably including Illyana coming out as gay and starting a relationship with Leah. Which would probably go really poorly, at first, since Illyana wouldn't be the Illyana that Sera remembers, but then there'd be some discussions and realizations that let them start fresh and find they do really get along well and work together.
