I don't believe that is possible. Everything has been done and everything is a copy or an variation of something that has been done previously.
Even if by some fluke something does come along that is original or fresh within 18 months you will have a hole cart load of copycat films.
Take for example Saw. A surprise hit and very gory, sadistic and bloody. Along comes Hostel then another similar gory, sadistic film.
As far as this film goes I think it's biggest problem is lack of recognition. Both Marvel and DC have their A-List characters. Even if you don't know some of them you may have seen their names on comics on the stand. For example if you had never read an X men comic you may know Wolverine by sight. You may not even know his name but he is on so much merchandising he is familiar.
One thing Marvel has alaways been good at is merchandising. Over the last 40 years they've regularly produced cartoons whether it's X-Men, Huk or Spiderman. This has allowed them to use lesser characters in those.
DC on the other hand have really always been known for that top tier. Superman, Batman (and Robin) Wonder Woman, Green Lantern and possibly Aquaman
If they are pushing to make films on popular among comicbook readers but unknown to the majority DC characters such as Jonah Hex I think they are really going to struggle.
Neither Watchmen or V for Vendetta really blew the socks off cinemagoers and came close to breaking box office recorRAB. I think part of their problem was again lack of awareness. Not being either Marvel or DC creations their popularity and to a large degree their entire existance belonged within comic book stores only. There was no brand recognition at all for the majority.
