I don't see why not. The first part would be the hardest part, methinks, as balance could be difficult to achieve. What do you have in mind for substrate and fertilization? No CO2, I take it?
I'm just thinking that it would be great if the only fertilizer you needed to add was fish food, and the only filtration/oxygenation you needed was the plants. This is probably what you had in mind, but you might be into "moderate light" territory. I have 8w/6g, sou you're definitely not as low-light as me...
