James Franco is known for playing movie characters that are arrogant, hot headed, and sometimes criminal. Known for some of his roles like Oz the Great and Powerful, Green Hornet, and the Spider-Man trilogy, he would certainly do the role of Quicksilver and take one the Chitauri one by one.
Mila Kunis would pull off playing a fantastic Scarlet Witch in the Acengers sequel since she played Throdora, the Wicked Witch of the west from Oz the Great and Powerful, and she was able to shoot out fireballs and red lightning energy and with a temper she would really nail it as Scarlet Witch and wipe out as many Chitauri as she can with her magic.
