I've seen people speculate that the engineer is Reed Richards - since F4 are back in the Marvel Studios fold along with the X-Men, that's a possibility too (not one I personally would want to see, but still possible). Or even Victor Von Doom (pre-evil?).

In conclusion, I would really really really like this a lot better if it was the story of a mediocre white man fucking around with forces he had no hope of understanding than yet another story of a powerful woman unable to control herself because of feeeeeeelings.

Agreed 100%!
