Sure, a book "like" this could me made today or at least, it could have been made last year. It's not like Marvel has been avoiding political issues. But, given the creators Marvel hired, it probably would have been terrible. And yes, I liked the original.
As for the N-word, no, it certainly couldn't be used today. GLMK was written at a time when intent mattered and people wouldn't so quickly disregard the context in which a word or symbol was used just to get offended.
No, I'm with Midnight_v on this one. This book was all about Iceman being gay and a very unlikable gay at that. I hated the way Bobby was outed and what it implied about past stories but I had hopes Grace would repair things a little, that he would have a more subtle approach after Bendis' trolling. Boy i was wrong.
