I think that's a great idea. In fact, there are a number of audio papers that address what might be considered texture for audio (including that one that we're going to look at in a couple of weeks). On top of "new-age" music, I it would be interesting to reproduce what I would consider "environmental" sounds, such as rain, the ocean, traffic, etc. I'm not sure if I'll have time to work it into the project for this class, but I will definately look into something like this in the near future.
