Again, no, line arrays aren't curved to control combing. They're curved to provide fill in the near field.
The entire definition of a line array is that the column act as a single acoustic source. The goal is to focus the energy and limit vertical dispersion. To do this the acoustic centers of the drivers must be closer together in the vertical plane than the wavelength of the driver's pass band. A primary difference between a common speaker for home or PA use and a line array segment is that the horns in a line array are carefully designed to emulate ribbons as much as possible. In short, having a bunch of domes or cones stacked up a plank of MDF does not a line array even remotely make, regardless of how much DIY'ers and some speaker companies claim it does.
I'd suggest folks go read some white papers and research on the subject.
