Some suggestions:
gr1 = ParametricPlot3D[{x, y, x y}, {x, -1, 1}, {y, -1, 1}]
The following will color the edges by average height of the polygon
vertices.
gr1 /. pl : Polygon[p_] :>
{EdgeForm[Hue[Plus @@ p[[All, 3]]/4]], pl} // Show
SurfaceGraphics objects, sg, generated by Graphics3D can be converted to
Graphics3D objects by Graphics3D[sg].
We can construct edges as lines and then manipulate the lines:
Show[gr1 /. Polygon[p_] :>
{Hue[Plus @@ p[[All, 3]]/4],
Line[Append[p, Last[p]]]
}]
