That doesn't accomplish the same result. If you take all the data from a broad-ranged hearing sense and squash it down into the normal human range, you will inevitably loose a lot of the information. You won't be able to hear the actual pitch of anything beyond the normal range, you won't be able to listen to all those different pitches at the same time, and you won't be able to hear patterns (like music) that occur across large frequency ranges.
As I mentioned in my post, this kind of approach is a good first step, and its all we can do with present technology, but it falls far short of what we ultimately want to achieve.

Same problem. The human eye can only distinguish a few million colors. If you have good IR and UV sensors you're going to need several tens of millions of new shades, and they just don't exist. You're software will have to discard most of that information, and what you're left with will be some kind of "hot things glow red, UV sources glow blue" kind of color coding scheme - which is useful, but not nearly as good as real broad-spectrum vision.

You can learn to pay more attention to your senses, which gives the subjective experience of receiving more input. You can't change the actual performance of the underlying hardware in your brain. The best you can do is make sure that you actually use all of the capacity you have - once you've done that, you're stuck until we get the technology to make improvements.
