If the buck you're after isn't overly paranoid and isn't on the brink of going nocturnal, good ahead and take a doe. This weekend, i got to my spot to find a gut pile in the field 150 yards from the stand. i just said the heck with it and made the 20 foot climb. I wanted to shoot a doe, but one got downwind of me(in the place they weren't supposed to come from) and picked me off when i started lowering my bow down. must have caught the movement and pinpointed me. you should be fine whacking a doe or two. it's probably better to get your herd reduced in the long run anyway.
