The filter would probably work, but I think it would be fairly expensive to get it up and running. I often think of just removing mine as I don't like it taking up the extra space in the tank.
I did remove mine when I first bought it to clean it out real good. Mine was just attached with silicone. A good sharp raiser blade did the trick. If you are going to remove it permanently you probably want to clean the silicone remnants from the glass. I think you can do this with acetone, but double check with someone else. I'm not 100% sure.
I also repainted the back of mine as it was a little scratched up. The filter and the back were both blue. If you are going to remove the filter, and are setting up a planted tank, I would strip the paint off and paint it black. Personally, I think black is a lot better for a planted tank. Blue is probably good on a marine tank. I'm not sure what you need to remove the paint. Fortunately, glass can handle some pretty strong chemicals. You can probably find something at Home Depot.
