Sump / Refugium - oversimplified??

Presently on my 55 gallon tank I have a 10 gallon sump that is just a 10 gallon aquarium with a Sealife Systems skimmer and return pump, plus a heater. I want to expand this to give me a refugium for plants (for water quality primarily), and to increase water volume. I have looked through various posts and seen many elaborate plumbing systems. What I am proposing to do is much less elaborate, but I don't see why it will not work. Tell me what I am doing wrong, please, before I start buying and building.
I am attaching an image, but I am looking at getting a 96 qt sterlite container ("clear" container like Rubbermaid) from Walmart or Target. Approximate dimensions are 34" long x 14" deep x about 15" tall; plus another sterlite container about the size of a large file box (maybe 10" x 12" x 12" high . . . perhaps a little larger, but a few inches shorter than the large box). This second box will serve as the refugium and be inside the larger box.
I am not using bubble baffles, because bubbles have not been a problem in the 10 gallon sump, so I do not expect them to be a problem here.
The picture shows the rest -- I hope. Have I oversimplified this to the point that something will not work? I plan to put sand, LR, and plants in the refugium.

The only problem I see is that you will lose pressure in your return by diverting it to the fuge. If you don't care about that, then your design is fine. If that is a factor for you, you may want to make the fuge a closed loop, and have a separate pump drawing out of the sump into the fuge.

Yeah, my plan is to put an adjustable valve of some sort (not sure until I get to explore the plumbing section at Lowes) that will cut the amount going to the fuge to maybe 5% - 7% but keep most of the flow returning to the tank.

That is almost exactly what I just built for my new tank, the only thing I added was baffles to reduce the microbubbles.
Here is a picture of the design

you could always not t off the return line and just use a powerhead to feed water to the fuge.. thats probably what i will do when i go to make mine.
