MikeG, I'm not sure if I totally get what you're saying. If you already downconverted to zero IF then you can't just take one of the I/Q channels. The volume will oscillate slowly up and down.
For a near zero IF use, you could do what you are saying, just be sure to use a VERY sharp low pass filter that has just enough bandwidth for the message signal. So if in RF, the carrier frequency is fc, the bandwidth is 2 B, you can downconvert to B, with a local oscillator of fc-B. This scheme will still let an adjacent channel trough.
