I am afraid that you cannot have the best of two worlds, or like they say in 
French: "To have the butter, and the money for the butter"  ;-)
Zooming in close to a modelled planet pushes your possibilities to the 
extreme and scaling your scene would not help. My advice for the groundlevel 
landscape would be to model a scene totally separated from the planet model 
itself but in accordance with its character of course. If you want to zoom 
in from planet-wide view to groundlevel-wide view in an animation, you will 
have to find a way to merge from one to the other in a satisfactory way.
