It is sad but Crystal is one of the most connected characters in the Marvel U and the most ignored. She is an Avenger, Fantastic Four, and Inhumans. She married into both the X-Men and into the Cosmic Realm. She's an easy custom but still would love a major release regardless of the costume. Aleta's light based powers would make for great accessories but again no one remembers her. You should get the trade of GOTG for Jim Valentino's run. I remember loving that book. Why not just make a Banshee two pack with both Teresa and Sean. It could even be a theme! Captain Marvel (Carol and Genius), Banshee (Theresa and Sean), Wasp (Hank Pym and Janet), Hawkeye (Kate and Clint),
a carol and genis set would be incredible!
and, if we're talking captain marvel/gotg/quasar/ignored characters, a phyla-vell and moondragon set would be a dream come true for me
