It's not as simple as that. Those typical ~720-730mm bars have a grip area of around 200mm. If you have shifter pods, you will need 170-180mm of grip area, i.e. you cut max to ~680mm, not much won. But it would be possible to imagine a narrower bar with tighter bends. Those 730mm have very relaxed, smooth curves, not very space saving.
