A paradox comes to mind regarding the group's plan for creating the X-blade.

If Young Xehanort is used, and can't go back in time aftwards, that would leave no Xehanort in the past to grow older and set up the events of the entire "Dark Seeker Saga". Sora, Riku, Kairi, and Lea wouldn't be Keyblade weilders due to the lack of Master Xehanort's manipulations during Birth by Sleep, and Maleficent wouldn't have been trying to take over the worlds.

The event would erase the current Xehanort, but because of that, it would cause the exact opposite to happen as well (read about the "Grandfather Paradox" - if you accidently killed your grandfather in a time travel visit to the past, you wouldn't exist; however, if you didn't exist, ytou couldn't have killed your grandfather) See the headache in trying to figure out how Master Xehanort i going to get past this little detail.

Well, if there's someone else besides his younger self that can fill throne, it would make sense, but if the X-blade is destroyed again, that would create a paradox, effiectively erasing all of the stories since there would be no more Master Xehnaort.
