With Kang the Conquerer being the big bad in Lego Marvel Super Heroes 2, I'd like to see him in MvCi. He has a lot of potential with his time travel powers, being able to summon all kinds of weapons, creatures, people, and other objects from across all of time.
Also, since his license is in a grey area, that could open the floodgates for other Fox properties. I understand he made it into the Avengers cartoon, but apparently they added him in without checking the rights to the character and didn't know he was partially/fully owned by Fox. In this case though, his inclusion was fully intentional and definitely negotiated.
Kang would be so cool, I imagine him summoning a neanderthal to beat up the opponent with his club, fire a blast from a 40th century gun, and then summon a brigade of revolutionary war soldiers to fill the opponent with lead. Or he could summon some golden age heroes/villains like the Whizzer, Bucky, or Arnim-Zola. He could summon the descendents of Marvel heroes and villains. He could also summon copies of himself from different time lines to function like Multiple Man. Sounds like he'd be work-intensive and highly unlikely though, but it would be an amazing inclusion.
