I'm a big fan of Red Oxx generally. How about one of their duffels? The Sun Chaser sounds like it might be good for your needs. The Flying Boxcar might as well. The Safari Benos line might be a bit slim for cubes - they are more for people who fold/roll and stuff/layer.
The Air Boss can probably take a cube on each side, if that is how you want to pack. SkyTrain is probably better for what you are looking for, however.

Yeah. The SkyTrain is probably more conducive to using packing cubes, with the larger compartment.
