I don't think so...well, you could do it all by hand, but it would be
extremely tedious, even using the blob_pigment feature. A modification
of the displace warp would be faster and tremendously easier.

The displace warp uses the gradient of the grayscale value of the color
of a pigment to determine the direction and amount of warping to do.
Instead of taking a pigment (pattern + color_map), it will be able to
take a pattern and spline, and get the float value directly instead of
converting colors to floats. In other words, using a spline {} as a
"float_map {}", mapping float values to pattern values.
