Does camera distortion support generic camera model?

Hi, all I'm trying to utilize distortion coefficients on fisheye camera simulation with generic camera model (opencv 3.0), which is (k1, k2, k3, k4). While according to the tutorial, gazebo seems only support brown's model(k1 k2 k3 p1 p2). so i'm wondering is there any solution or plugin to make the image more accurate to the real condition? Thanks!!
