Captain Morrigan

Ok, so in the new Marvel vs Capcom Infinite trailer, they hint that the big bad might be Sigma. Some people have speculated that it might actually be a hybrid of Sigma and Ultron, hinted by the glowing eyes in his chest.
This got me thinking, since the game focuses on 2v2 fighting, what if one of the new mechanics is FUSION! Characters combine with each other to form new characters!
Megaman + Ryu = Mega Ryu
Iron Man + Captain Marvel = Iron Marvel
Captain America + Morrigan = Captain Morrigan???
