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.
