If you have a good run of weather and the bees consume a good portion of what they have in their hives, you may want to feed a little more. For what it's worth, I leave my top feeders on until it's cold enough, consistently enough, that if I'm feeding the bees won't come up to take it any more. Then I pull becuase of the condensation issues.
It's also a timing issue for you, though. If you're comfortable with what the bees have in their box and you have time to swap all the equipment around now, and not later, then go for it. There are other feeding options if you need to supplement.
