Ever since Ryan Reynolds was Hal Jordan the very first Green Lantern on earth many have actually wanted John Stewart to take up the mantle in a Justice League movie. Why? Well 90% of the time the fanboys actually grew up on Stewart from the Justice League: Unlimited TV Series and say he is a better Green Lantern.
Now the number one actor most see as John Stewart is actually Idris Elba (Thor: The Dark World) even though rapper Common was going to play him back when Justice League: Mortal was in development. Now someone sent out a tweet to Elba with a Photoshopped image of him as John Stewart and he actually likes it!

If they do a full reboot again then they would have to go back and redo Hal Jordan the first Green Lantern all over again which is unpractical.
