By using fundamental units as conversion factors one
can easily transform the dimensions of all observables. In
particular one can make them all "geometrical", or
dimensionless. However this has no impact on the fact that there
are three fundamental units, G being one of them. Only
experiment can tell us whether G is basically fundamental.
