Might the Khan have let the Dark Eldar capture him?

An Interesting theory, but I'm afraid I haven't much to say about it. Though he might have also been taken by Harlequins like others have said, to the Black Library and can't get out again...

Everything is possible, it`s a never-ending story of possibilities limited only by the edges of self imagination. ( Combat drugs really affect me sometimes )

truth of the matter is that we will never know...., knowing what games workshop is like after all...more change of them bring back the Ultramarine one than the khan..

I disagree. Look into Space Wolves chapter creation, analyze: How do they become to life in this realm ? The answer of this question will bring you to the essence of the core that move this world. It will show you the route from fluff to the table, as one mechanic of the Warp !

Total commercialize on the Ultras since they are the 2nd most known space marine chapter.
