There's a million hours of stock footage of the Manhatten skyline pre 911.
Sure, but in HD? Probably, though it could be harder to get hold of, and might stick out as obvious stock footage when thrown into the mix.
... Moreover, the target demo for the show is probably too young to notice the towers' absence. And it's pretty much impossible not to wince now when you do see pictures of them, thus creating tone issues. To take it to an extreme, one could posit the show takes place in a reality in which the towers were never built in the first place.
But I grant it is
kind of strange.
