So I had to look up Barbara Ketch and Xavin, as I don’t really read Ghost Rider or Runaways (I know, I’m a bad comic fan. But I’ve really been meaning to read those series.) But any of those characters you’ve mentioned would make sense as potential Avengers.

Honestly, I don't have much knowledge of The Runaways, only basic info on each member. Xavin intrigues me in a similar way that the 1610 Jessica Drew does. Jessica is a female clone of Peter Parker with all his memories up to her creation. Xavin, who has lived his life as a male, makes the decision to switch his gender after falling for a lesbian teammate.

I have only slightly more knowledge of Ghost Rider. I enjoyed reading the comic way back when Danny Ketch of Ghost Rider, including his team-up with Wolverine & the Punisher vs Blackheart and his short-lived membership in the Fantastic Four (alongside Spider-Man, Wolverine, and the [gray] Hulk).
