My thoughts about a Xehanort with a keyblade
Ansem himself could not wield the keyblade as a heartless, so he possessed rikus body to wield the keyblade once again....so Ansem(Xehanort) at one time had to wield the keyblade...maybe that is how they performed the experiments on peoples hearts, Xehanort unlocked them, thus leading to them knowing about kingdom hearts.....but i have one conclusion......if there are always a key to the light,key to darkness, and the way to dawn, sora just got the keyblade and so did mickey, riku did not get his until after kh:com.....meaning that once ansem(Xehanort:Heartless form) was defeated, the keyblade moved on and picked Riku.....that means that Ansem could in fact have defeated the keyblade of light before sora, and mickey and kairi, meaning they had to move on...and picked sora and mickey....and kairi(i have no clue where her keyblade came from)
