another thing came to mind, which could use Raven's power to simulate that he is aging and later in life he could simulate his death but also that he has adopted himself again so as to always have an identity linked to Stark. For TV series you could add practically all of them as most of the various films take place more or less, however it is not mandatory to follow every episode in detail. By adding the TV series Agent Carter you could not only get closer to Peggy but also join the SSR and then the Shield
It occurred to me that exposing him so early that he's a mutant isn't a good idea anyway, after all he could ask him to stop for example the erskine killer as well as ask about the serum he already has, but you could have him erase that memory when he gets Charles' power, but you could make it seem like he adopted it because of his intelligence. With the power of Charles and Raven you could infiltrate all the organizations and obtain their technologies, secrets etc... as well as learn from the greatest minds. He could gain Wolverine's power so he could still be young in the 2000s. He could learn both magic and chi manipulation. As a personality I hope he is an anti-hero.
