I like that idea, but how do you handle data that already exists in your database? So, you are using your setter to establish the instance data, correct? The data that comes from your database is sent through your setter when you are establishing your instance data?

For instance, as someone else said I might have a predefined, application wide value that is a "null" integer (a magic number like -1 for instance) my setter takes a string but my getter returns a numeric. If my setter gets a non-numeric value then it sets the value in the instance scope to be equal to my magic number. If it gets a numeric then it keeps it what it is. My getter always returns a numeric.
