Maybe at the next linewide event? Miles and Kate ended up on a team together in War of the Realms, and obviously the majority of the two teams have met at Nadia's birthday party in her solo book, which ended with the two teams having a team-up. So they already know each other.
In the late 2000s, the YAs had two team-ups with the Runaways (in Civil War and Secret Invasion), but that book is more slice of life than superheroics nowadays - they didn't even get affected by Outlawed. It would make sense for the YAs to team-up with the Champions instead, but Kamala's Law has to go away first. Outlawed was responsible for the Champions missing both Empyre (Kamala was still in her coma, the event seems to take place between Outlawed #1 and Champions #1), and King in Black (Kamala got infected and Miles rescued her in his book, the rest of the team sat it out). The team was also splintered during both Secret Empire and War of the Realms (they did have tie-ins, but several members were missing from them). If the two teams were to join forces, it ought to be when they're at full strength.
