You could try that, but it doesn't work very well. During the compilation process, the maps are broken to pieces and many of their "faces" are destroyed. Thus rebuilding MAP files from limited BSP files is a rather painful process and doesn't really get you good results.
Why are you trying to do this, anyway? Are you trying to steal map files from Quake or something? Because those have been GPL'd and you can just download their source files right off the internet now for free. You just can't use them in commercial products and stuff.
