I was wondering the attitude/disposition towards the idea of "Dark" Wood Elves.

After reading Malekith (though not any more of the series), it makes it pretty clear that a large portion of the old world "colonies" were founded by Nagarythe, and it's certianly implied that Morathi infiltrated the Cult of Pleasure into them.

If so, is it not possible that some Nagarythe colonies survived, especially those isolated from the others, and after the withdrawl of the HE, could have grown into a 'dark' version of the WE? Or is that stretching the background too far?
