I agree. I don't like having a large cartridge, but I guess for some it is necessary.
The problem with using a square or other pressure vessel with corners is that the pressure inside will equally distribute and cause it to expand to a cylinder anyway, which may cause it to burst. If I were you, I would just go with a cylindrical one that holds the same amount. There is less chance it will burst and it will probably hold more in about the same amount of space.
