I'm gonna completely switch stuff up:
My 8-member Alpha Flight would be:
1. Vindicator (this'd be Windshear wearing the Guardian armour) - Mac and Heather would both retire from superheroing, just help run the team and do scientific research for Department H, etc.
2. Box (Roger Bochs - I'd find a way to bring him back)
3. Puck
4. Talisman (I'd continue her relationship with Puck, and have them dual-lead the team in the field)
5. Citadel (prison work-release program)
6. Aurora
7. Snowbird
8. The Shroud (why not?!)
- Sasquatch would be more interested in science and trying to reverse the effects that the Sasquatch transformation is starting to have on his body, but he would be available to stop in and help when needed. Northstar and Jeffries are too entrenched in the US of A to be returning to Canada, me thinks.
Beta Flight:
1. Shaman, their leader
2. Ghost Girl
3. Flex
4. Yukon Jack (and I STILL think it'd be funny if he was in love with Snowbird)
5. Epsilon Red (Jeff Brown, wearing a new suit of Epsilon Black armour with a red motif)
Just noticed your post, Tawmis - in particular, "perhaps work on a relationship between them (where he wants her, but she wants nothing to do with him, remaining the aloof Snowbird I enjoyed)."
I believe we are thinking along the same wavelengths, or close to it!
