Let me get what you want straight:
You want ALL images to be grey scale, not just covers?

For that, you need to Unpack (U in Calibre), process the images with you favorite tool (I used to use Paintshop Pro), then save (the Unpack tool has remained open all this time). Note: This process is performed on the LIBRARY COPY, COLOR IS GONE for good
