Love seeing all the mentions of Hellion and Frenzy! I just remembered that Jean and Joanna teamed up briefly to go to Genosha and face Magneto (along with Omerta, Northstar, Sunpyre and Wraith).
Northstar and Omerta would be interesting to see on a team with Jean again, for that matter.
Colossus is one of many in Gold that aren't getting much play, it could be neat to see him move on to team with Jean. Her fastball special involving telekinetically throwing *him* would be a heck of a lot scarier than him chucking Wolverine...
