It *is* possible to have displacement be independant of gradient...just 
displace the coordinates you give to the blob function, instead of 
adding to/subtracting from the function. Use 3 displacement functions 
with outputs from -1 to 1, each one offset a bit so it doesn't 
synchronize with the others, and add their results to the blob function 
coordinates, multiplying by another function controlling the strength of 
the displacement.

function {
    BlobFunc(
        DispFuncX(x, y, z)*StrengthFunc(x, y, z) + x,
        DispFuncY(x, y, z)*StrengthFunc(x, y, z) + y,
        DispFuncZ(x, y, z)*StrengthFunc(x, y, z) + z
    )
}
