And I've used and built a scrubber also. The concept is basically the same. The only thing is your not adding additional plumbing and pumps, along with an additional piece of lighting. Add to that, it's a different type of algea..
Really, it's surprising to me that neither anyone else has tried it with any success(I can't be the only person alive that has done hydroponics and aquariums) or has shared this info previously.
Personally, if I had a remote fuge/sump/water change, I'd simply light it with a 400 sodium. That will grow anything, and your only confinement it's going back and forth one you realize how often you need to pull it. But on the flip side, someone is "always, always" looking for good, dense cheato. I produced enough to supply a fish shop, but I grew tired of dealing with it. All from my little 110 and 30 gallon(actual water volume) sump.
