The "SetTuple" interface is provided in the vtkDataArray superclass for 
use without downcasting.  The "SetValue" interface is provided for the 
subclass types by vtkDataArrayTemplate.  However, there does not seem to 
be a "SetValue" that takes a tuple of the correct type.  Please submit 
this as a feature request here:

and you will automatically be notified when it is implemented.
