Maybe Guardians of the Galaxy for Karolina (since it looks like she might be off to space), New Mutants for Molly (she is a mutant, after all), Amazing Spider-Man for Nico (considering that apparently, Doctor Strange is giving his responsibilities to Ben Reilly, and I'd hardly call him and Black Cat magic experts!)? It'd be interesting to see Victor Mancha show up in Champions due to his antagonistic relationship to Viv Vision (Victor killed her brother Vin in Tom King's The Vision!)
