YES or NO and WHY?
Myself: Yes, I've known the universe of WH40K for just over a decade now and have become bored of the supposedly "unique" setting and "Grimdark" nature. Video games and certain novels have already made way for a much more interesting story. (personal opinion) Sandy Mitchell's Ciaphas Cain novels embody this with an actual sense of humor and action whilst retaining setting and suspense. What most people seem to forget when loving their disgusting "Grimdark" setting is that, regardless of any setting, universe, rediculous faiths, cults threats to humanity, mutants, etc., that humans are still human. Often people cite that any form of love-making is instantly involving Slaanesh, or enjoying the slaughter of your enemies is on grounds of Khorne worship. Too often do I find other forum surfers spouting their bull about how "this is heresy" or "this is right because that is what makes Warhammer 40k unique". They sound the voracious radical Inquisitors that hinder the Inquisition.
(also opinion) Note: Warhammer 40K was unique in the 90's. With the progressive medium of good videogames and excellent writers, sci-fi fantasy is mainstream…in essence.
