Maybe I'm misunderstanding, but couldn't you just use xrandr to change the viewports for each output so that a few pixels near the edges overlap and get sent to multiple projectors? Maybe the overlapping sections might become a bit brighter having the same pixels drawn by two projectors, but I guess you could just overlay a fixed rectangle in your code with the right alpha value to dim those pixels to compensate.
