Oh, I know, Philip Glass did it first, plus, nice 3 against 2. But here's the thing, a musical style that is easily duplicated is not a very interesting musical style. This is one reason I would say that Vivaldi, for example, is a less interesting composer than Bach. It is not very hard to duplicate Vivaldi's style, but very, very hard to duplicate Bach's. Beethoven did a fair realization (which is better than duplication) of the style of Mozart and Brahms sort of did a realization of Beethoven, a long time later. But other good examples are rare.
But there are a thousand duplicates of the style of Philip Glass and Michael Nyman out there:
For one thing, Nyman is pretty much a duplicate of Glass already...
Steve Reich is less easy to duplicate because it is a more interesting and developed musical vocabulary:
