But to answer the original question, yeah, for sure you can make a top beer using kit yeast. You just have more control (and probably more confidence) using specialty yeast.
What makes an ale or a lager is an ongoing timeless debate which is much more than this board can know from its members. Right at this now, yeast biologists are getting into bother about this very question very much right now but what you are saying is still very much correct.
Strains of "wheat" yeast are those that are producing the right phenols and esters for Weizen beers in Germany and there are interesting Belgian yeasts for making Wit. They are different yeasts indeed but all ale yeasts, it is true.
K-97 is not at all what you would be using to make Weizen, Weissbier or Wit. Just search the WWW if you are not believing me *chuckle*. It is a very neutral yeast (it is not producing much phenol or esters) and is very nice in a pale ale beer with tettnang hops. I am not knowing why Mr Mel at ESBeer.com.au is calling it "SafWheat"? Maybe to make a dry yeast for wheat beer as there are not other dry strains of similar available now?
Much is there to know about yeast!
One thing that I will say before leaving this topic for fermentation is that the types of yeast one is finding in kits and sachets all dry are the types of yeast that dry without dying. According to my limited understanding of this, that is the thing that makes a yeast be chosen for drying - it can come back again. White Labs and Wyeast have many many types of liquid yeasts that are being sold as liquid yeasts only because they cannot survive or keep all of their properties after drying and rehydrating.
