I think that's pretty likely actually. Ewing wrote Sunspot as the leader of his US Avengers and his Guardians run is gonna incorporate the major space empires. I think a crossover is nearly inevitable at this point because the Shi'ar are gonna play a role in both franchises going forward. And even if there's not a direct crossover, I definitely imagine that some characters or plots might be explored across both titles. Like I wouldn't be surprised if we see the seeds of the Badoon/Shi'ar rivalry from year 1000 in the Guardians book. Or if an X-Men joined the Guardians or vice versa.
