Re: what now?
I would not move the 1/2 brood frame down. The bees need open comb for cluster space in the top center to help them move up into honey during the winter. They need open combs to cluster into. This is so some bees can sit head first into the cells to warm the comb and brood and the clustered bees.
I would move the outer undrawn frames (I'm assuming the undrawn frames are to the outer sides of the box) in more towards the center of the top box. I would not move them down into the bottom box. Moving them more towards the center will get them drawn faster instead of so much backfilling of already drawn combs.
I would then keep feeding until all frames are drawn.
I am not in your area and do not know your flows timing and do not know your weather. We are getting closer every day to winter solstice. Here in my area, It's hard to impossible to get them to draw comb at this time, and the over night lows are getting colder with daytime highs getting cooler. This being the case, perhaps my advice is not perfect for you.
20+ years, raise my own queens, feed when needed. I treat, but have not perfected varroa management yet.
