So what have you changed aside from the layout? I'll assume the lighting is the same. What do you plan to do about algae? From the looks of things, that light is going to cause it with that few plants. The light is so close to the tank you'd need a lot more plants to combat it... lifting it higher, if that's an option, may help. I wouldn't want you to make the same mistake because I know battling algae is draining and no fun. Changing the layout but keeping all the same other factors will not stop algae so some more strides have to be done.
Being emersed right now you won't get that problem, but once you fill it up, I feel like that is too much lighting too close. Looking at the tank you referenced on your first message, you can see that their lighting (granted it's different) is way higher: Mythin's Mr. Aqua 12 Gallon Long (Flooded 9/13/2012!)
I think you'd benefit from lifting at least a few inches, if it 5+ inches.
