Whilst the file is 3 times larger, what is the point? Just because
there is more data, that by itself gives you no advanatge. You coulld
always scan in 16 bit grayscale, and then change to RGB in PS.

The advantage that it might give you is that one of the channels on
the scanner might be a little noiser than the others. By not using
this channel, you might get a better image. That's the theory anyway.
But, if you use Vuescan, then you can then control which channel to
use, bit still get the smaller file sizes associated with grayscale
images instead of RGB file.
