Those bass bin mods will be just fine. I get really cautious with mods on cabinets that are exposed to midrange content, because midrange standing waves can create issues. But the bass bin of the constant directivity cornerhorns is insensitive to these things because it is crossed-over pretty low. Wavelengths are long, so little 1" shifts are acoustically invisible.
