I know this is not the best way to do this but I am asking anyway; Would changing the brake fluid in the resevior only be worth doing? Does the fluid circulate?

No and no.

You wouldn't be accomplishing much by just changing the fluid in the reservoir.
It will look better but the nasty dirty fluid that was in the reservoir is still there in the entire system.
The fluid does not circulate in the usual sense of the word. It only moves slightly back and forth with brake use. The contaminants and moisture do migrate thru the system and probably collect in the lower extremeties of the system(calipers and wheel cylinders.) You have to open the bleeder screws to be able to flush out all of the old fluid while adding fresh fluid simultaneously. You have to be careful to not let air get into the system. It's not that hard to do. It helps to have an assistant but you can do it yourself with a little careful planning.
Email me if you want specific instructions.

you can take the resovor off and degrease the inside and outside andclean with water and make sure its really really dry before putting it back on.
under certain conditions, you wont even have to bleed afterwards.

www.speedbleeder.com are nice to use when doing a bleed/flush of the brake fluid. When doing a flush I like to get all of the brake fluid I can out of the reservoir first prior to adding the new fluid. I use one of these:
Haha... I JUST bought one of those at K-mart yesterday for this exact purpose. Great minds think alike!
I siphon/refill my master cylinder with every oil change. This makes the yearly bleeding very quick since the brake fluid seems to stay clean everywhere. All fluid is connected and there is reasonable fluid movement/displacement to justify this. Brake caliper pistons take up worn pad space with fluid. Clean fluid is better than saturated fluid. This helps with caliper/master cylinder life.
Any miniscule moisture removal with this method only helps.
Trying to do this for a quick fix is time wasting.
Being consistent is the key.
With the siphon, I had to use a basket/soccer-ball filler connector from the tire pump. The syringe/hose do not reach down far enough. The borrowed tire pump basketball filler allowed almost complete master cylinder siphoning.
For thorough brake bleeding, always siphon/refill master cylinder. Speedbleeder makes clutch/brake bleeding a piece of cake for anyone.
