On my big tanks, I run 2 canisters - one at each end. One pushes water across the tank to the other. Its kind of what you are talking about, though in a smaller tank (less than 4 feet, but not a small tank) a power head would be a better choice to achieve similar results. Works very well for me, and the many others that do this on other forums. It's frowned upon here though - not sure why I'm even mentioning what I do as I get blasted for it. In any event, in a 10 gallon tank, I would not use a power head any more than I would use a second filter. However, a small sponge filter will circulate water through a dead spot. If you are looking for a new filter, my recommendation is the Tom rapids mini canister. I suggest modifying the spraybar to reduce current though, which can be done by making the holes bigger, as well as drilling holes into the back of the spraybar, and also on the end cap.
