WGS84 defines an ellipsoid that is used for a reference to approximate the shape of the earth. If you are talking about a fictional planet, you can use anything, a sphere.
A real planet, at least one that is out of round enough, and with data good enough, for the data available to be in error, will have to have it's own ellipsoid defined. (A sphere would probably do for most of these for some time to come as well) Your problem would be the radius, unless all your planets are the same size. But you could do a scaling fixup fairly easily (I believe) to server your purposes.
