Instead of using the SphericalPlot, try using the ParametricPlot3D.
You can do it in this way (assuming theta is longitudinal and phi is
asimuthal):
ParametricPlot3D[f[theta,fi]*{Sin[theta]Cos[phi],Sin[theta]Sin[phi],Cos[phi]},
{theta, 0, Pi}, {phi, 0, 2*Pi}]
This will create a point distance f away. Works nice for plotting
spherical harmonics, although you might want to adjust the PlotPoints
parameter to get nice looking results.
