You've got to try these things Fred. I'm not going to say its impossible, but performing BVR imaging as a replacement to conventional RGB takes some effort. I went to the extent of also collecting data on a G2V star so I could confirm my colour balance suspicions, but still found it difficult and failed. Hey, and lets face it, elementary filtered RGB can get tricky at times, especially when you've got an individual channel with a gradient that offsets the other two channels. If not corrected carefully, it results in a different colour balance ratio as you've changed pixel values. Those OSC (one shot colour) guys almost have it too easy.
Not sure if you've seen the work of
Stephane Guisard. He seems to have mastered the BVRI imaging - http://astrosurf.com/sguisard/
