I suppose I'll clarify a bit

This app will have a small user base (<6), and will be in a controlled environment.  That said I don't intend on switching objects that often, but approximately one in every 1000 objects created would have to be changed due to data entry errors.  Ultimately the object type should be set for life, save for the occasional error. 

It seems to me that it'd be easier to handle the errors generated when fetching/saving, rather than create and maintain a helper class.

My personal advice... Don't do it.
2nd that .. It's almost always a red flag of an incorrect design.  Objects rarely change types, but they often change roles.  It sounds to me like maybe your model isn't quite right here and those objects should have another relationship that is changing rather than the intrinsic property of the object.
