Multiple views is definatley the way to go.
I've done table updateable views, but only for updating a single table and having the child or parent info in the view for display purposes. I would never change a primary key in a view, indeed I'd never change a primary key at all once it has been created.
Sounds more like you need a paramerterized view that is requeried based on the parent tables primary key.
