Oh, I can confirm the What If... issues. I have both of them. The Dr. Doom one is really good, just a little cameo for Sasquatch and Puck, well, the back of Puck's head really,... but I really like the story, one of my favorite What If... issues. Here is a pic of Sasquatch from a battle scene with Doom:
The Archangel one, issue #101, that's a debatable Alpha Flight appearance..... The twins may appear as members of the Marauders, standing around in a munitions warehouse. Northstar may be seen in the shadows in 1 panel and in another, what may be Aurora's right hip appears. A white starburst on a black costume is very clearly visible, but her face isn't. Northstar might also be standing to her left but unfortunately, a large speech bubble blocks a full view so we can't really see. Should a copy of the original artwork without the speech bubble surface, we could have a clear view. I'm going to say yes, it's them, you decide:
