How about adding a container around the geo that specifies the planet 
(or geoid, if you want to get extra fussy. You can say it defaults to 
WSGS-84, which is backwards compatible).

That way you can specify the planet once for a series of co-ordinates. 
What you do for  highly non-spherical bodies can be deferred, as after 
all the IAU now insists that planets are spherical...
