I would suggest keeping the two operations -- outlining and color
smoothing -- as separate operations.
If you duplicate your layer and, on the top layer perform your edge
detection, followed by a desaturation and color removal, you will be
able to erase (or enhance, or de-emphasize) the outline as you desire.
On the lower layer, try the Selective Gaussian Blur to smooth out the
Using the above technique (crudely), I was able to produce the
