Actually just realised you could do this with glass too. All you'd have to do is have a normal overflow in the corner then another piece of glass infront of it to take water from nearer the base. It'd work great and no surface skimming.
On that subject I'm not sure it's really be too bad on the CO2. As long as you don't have a trickle filter which really will gas off all the CO2 but the water running in under the sump's water surface then it wouldn't be too bad really. I'd just rig it up with a CO2 reactor on the return pump to make sure the water going back is full of CO2.
