Hellion and Johnny Storm would be comedy gold, two guys with the highest opinion of themselves this side of Emma Frost, forced to work together?
But yeah, I do like to see some interconnectedness between mutant heroes and 'everyone else.' Torch and Daken had an interesting relationship. Spider-Man has had ties to various students (Rockslide, Hellion, Ernst, Martha Johanssen and Shark Girl) and has a more funky relationship with Wolverine (after their *great* crossover / team-up involving the spy Charlie years ago). Northstar and Aurora started out their careers working with various non-mutant heroes, with a government agency (Dept H) that actively recruited mutants (like Diamond Lil, Madison Jeffries, Flashback, Smart Alec, Manikin, Stitch, Pathway and Goblyn)!
