I am closing this inclusion debate as spurious. The OP clearly states that they have not read these stories in full. Opening inclusion debates without having the knowledge of the stories, based on partial information, invites bad-faith inclusion debates of which this wiki had had enough. Thus, such attempts will be exterminated.
As a more general comment, origin stories and/or continuation of stories of crossover characters are generally considered invalid, with very rare and very well argued exceptions.
This wiki is not interested in Marvel UK characters for their sake. They should instead be represented on Marvel wiki.
