I'm pretty sure the answer to this is no - it is by no means a simple divide by 2. The author of libsamplerate (Erik de Castro Lopo) gives a series of lectures to my audio engineering students and demonstrates how important the filtering and conversion process is so that aliasing artefacts don't appear after the conversion, and shows an example of why this sort of method can add some very ugly modifications to the signal. I should see if we can knock up a graph (similar to those at http://src.infinitewave.ca/) to demonstrate this.
