I'm actually interested in Spider-Gwen (the costume looks nice anyway). Elseworlds stories always make me curious. 

For example "What if Superman crashed in Soviet Russia?" you get "Superman Red Son" or in the case of Mark Millar his comics are "What if [insert comic book character] was a jerk?" they are good fun.

If you want something like that take a look at the Flash Point plot line.

Flash uses his super speed to break the flashpoint barrier (timetravel) in order to go back and save his mother from being murdered. Trouble is damaging the flashpoint barrier is an incredibly volatile way of traveling through time. It causes ripples out from the point of contact. So Flash's mom lives but other things change drastically.

Superman's ship misses it's mark crashing into the center of Metropolis instead of Smallville leading it and him to be commandeered by the government. Bruce and Martha Wayne are murdered by Joe Chill instead of Thomas and Martha leading Bruce's father to become the Batman. The Amazon's and the people of Atlantis make contact with eachother without neutral supers like Superman, the Flash and Batman to ease tensions and a full scale war breaks out with humans caught in the middle. Atlantis floods the British Isles, Amazon's conquer Paris naming it New Themyscira. Things spiral from there, shit hits the fan hard.
