Surface Force already supports 3D maps. Just enable "surface offset as W" in the Texture rollout.
Mapping coordinates are composed of 3 values: UVW. The UV coordinates will be sampled from the surface and the W coordinate, when that mode is enabled, will be the distance between the particle and the surface. Then all 3 values can be used to sample your 3D map, whereas a 2D map only uses the U and V coordinates.
