You can "expose to the right" or anywhere you choose by using exposure comp in 
any metering mode. The metering isn't based on jpeg or RAW. It's based on the 
light and what's in front of the lens. No meter is smarter than a photographer 
who understands how meters work. 

Perhaps, I'm missing something, butI don't know what you men by choosing 18 
percent gray for shooting jpegs. You can use the spot meter and take gray card 
readings if you want a pure 18 percent gray exposure read. A histogram based on 
the raw might be nice, but it's not hard to interpret a jpeg histogram in terms 
of where you'll be with RAW. If you're edge to edge with jpeg, you're pretty 
much golden with RAW, and if necessary, you can push it beyond that a bit.
