IMO this is the wrong approach. The correct way to do this would be to 
implement a new GiST opclass for the higher dimensions which is likely 
based upon the contrib/cube operators and operator class. Then users 
specify at build time what dimensionality they want in the index and we 
can match an existing operator class API/behaviour for migration purposes.
