Including cross-casting?

That is, in Java (or C++), if I have class C implements I1, I2
and I have an I1 reference, I can try casting the I1 to an I2,
and if the reference is actually to a C object, the cast works.

The attempts to simulate MI in Ada by using access discriminants
don't handle this, as far as I know.
