Assuming a full repaint for Nightcrawler, I think it's about 15-20 new parts altogether:
Chest / Overlay
Alternate Flame Hair (?)
Alternate Head (?)

They might reuse Lady Deathstrike's upper arms, but I don't think we've seen 80s Kitty-style forearms for the short female body.
I doubt they will stand on ceremony and not place a figure on those retro cards that wasn't on them before.
IIRC, they already haven't. I don't think late-80s Dazzler, Madripoor Wolverine, and gray Beast were part of the 90s toy line.
