What i mean is, that if a class is implemented with a pimpl
structure using boost::shared_ptr this

A a;
A b(a);

would result in that changing private members of a changes
private members of b, which one doesn't want
in the default cases of pimpl.

No, scoped_ptr is noncopyable. Whats needed is a
template with deepcopying the parameter struct (or cloning)
and no need of an complete type at the point of the declaration
of the pimpl.
