Weirdly enough... as a player of both systems... I drool in glee at the thought of a 4e D&D version of Shadowrun.
It's not the mechanics that matter that much... simpler mechanics wouldn't hurt that bad. It's the stories that matter... as long as the adventures were well written and Shadowrunny, the fact that street sams had at-wills, encounter and daily powers wouldn't phase me a bit.

Of course the mechanics matter. Because the mechanics have a hand in the stories. The mechanics define how the world functions, they resolve the conflicts, which is what actually produces a story. Conflict + resolution = story. Perhaps it would be better put that there is more than one set of mechanics that can evoke the spirit of the 6th World. In the same way that 4e retained so much the spirit of 3e while seriously reworking the nuts and bolts of the mechanics.
But D&D 4e? Well it's built for different kind of world. It does have things going for it, such as being "team" orientated. But it's gridness, which is fairly integral, and a few other things aren't the best fit for SR ranges and such. There are more appropriate choices out there.
