That's actually easier then you think due to the way the images get processed with the profiles.
What you do is copy all of the images. Run with the RGB profile and any image that come out with 0 bytes is greyscale. Then take just those images (the original versions) and run them through the greyscale profile. Then put everything back where they came from and done. You can also do it in reverse as well. RGB processed with the greyscale profile also come out 0 bytes.
An ePub (the one I sent you) I just optimized (using the profiles) came out with the images totaling 334KB. The same images using ePUBOptimizer came out to be 340KB. I know 6KB isn't a lot, but it does add up.
I'd be happy to test if you decide to do it this way.
