Small variations are okay with me.
Leg stripes may be adjusted from year to year, as long as there are never more than two, and they aren't any wider than the current uniforms ('02 was a joke, except that nobody laughed).
Shoulder stripes, player's number or "N", whatever. Doesn't really matter to me. As long as red jerseys are worn with white pants and vice versa. Leave the all-white stuff to Penn State. The all-red uniforms from the OU game in 86... I've seen pictures, and it doesn't work for me. Not a fashion expert, but it just doesn't work.
The helmet could, for a game or two, and in conjunction with a throwback jersey, go back to NU. But you have to promise me it will be changed back to the simple, classic N.
When I think of great uniforms, I think Alabama. Penn State. Michigan. Oklahoma. But the best uniform has always been Nebraska (well, except in '02).
Imagine being at a meeting where they decide to add or remove a stripe. How weird would that be? You know that it's gotta be a meeting of at least a few hours. Somebody's really excited by the prospect of adding a stripe, someone gets totally cheesed that it even gets mentioned... Man, it'd be like this thread.
