You won't have issues per se. But from a practical standpoint its kinda... well, impractical. Usually people do a square wheel setup so they can run the same size tires, and easily rotate them, they also usually handle a little more predictably on a track.

Running the same size tires on different size wheels will kinda put you out of being able to rotate easier. The idea of buying staggered wheels/tires is to have more contact patch in the rear. You see this most often on cars with more power and RWD (corvette, m3, etc) - 86s that aren't turbo/supercharged don't really need this.

Again, its fine, it won't hurt anything and its cool if you just wanted a "look" - It'll be kinda pointless tho if you ever choose to track the car.... or rotate the tires.

Oh, NT05s ARE INDEED LIGHT, they also are very sticky for a non r-compound tire (ran them for HPDEs on my C5 - loved em in the dry) and they wear FAST - Fast enough that I wouldn't buy them again for street use. JFYI.
