Re: Race changes that wouldn't bother you
That's a pretty good breakdown Zarek. There's nuances in each group. Ie, It's a lot easier to change Human Torch, a relatively minor character who's race is incidental, than it is to change Captain America, a more well known character who is at the forefront of the military in WWII.
I think the most "controversial" changes I'd be up for in the Marvel Universe are:
Any 2 members of the Fantastic Four
Any Done Before in other adaptations
- Janet Van Dyne
Any Aliens Really
- Silver Surfer
