Don't forget the other signature, which cannot you cannot override
with a different type:

double *GetRange();

It's reasonable to provide a method such as the one that you ask for,
but only if the method name is changed.  So vtkIntArray would have the
following methods added:

void GetValueRange(int range[2]);
double *GetValueRange();

Ditto for the other arrays.
