I dont know if this is helpful but... I once read an article last year about a screenwriter who wrote a spec based on a comic book... now, he CHANGED all the characters' names and changed the plot around a little bit... and when he sold the spec to a studio, they decided to use THAT actual comic book and they got the copyright, so he was able to change the characters' names back to the original names from the comic.
So I guess, if you wanna write a spec based on a comic book, you should probably change all the names and maybe change it around a bit.
