I have to agree on the whole Mythos thing. Although for different reasons. You're right that Kyle had no connection to the Green Lantern. But in all truths, neither did Hal. In fact, the only Green Lantern who really had a connection to the 'Mythos' was John Stewart, the Opener of Doors (Guess what that alludes towards?).
But I disagree that Stewart was the logical successor. He was already a Green Lantern. What's the point of passing the torch, so to speak, to another Green Lantern? My point is, they NEEDED to get away from Hal Jordan. He was too good. And Stewart was a lot of the same. Besides, he was already the frontman in the Mosaic storyline of the early nineties.
There is also the matter of the aforementioned Morrison's JLA: Earth 2 storyline, which supports my standpoint; Kyle's fear is the very thing that made him great.
